chore: remove std directory (#9361)

This removes the std folder from the tree.

Various parts of the tests are pretty tightly dependent 
on std (47 direct imports and 75 indirect imports, not 
counting the cli tests that use them as fixtures) so I've 
added std as a submodule for now.

-## Discussion
-
-This is very much a work-in-progress. I'm actively soliciting feedback.
-
-- What useful features are available in other languages apart from Golang and C?
-
-- behaviour of `%v` verb. In Golang, this is a shortcut verb to "print the
-  default format" of the argument. It is currently implemented to format using
-  `toString` in the default case and `inspect` if the `%#v` alternative format
-  flag is used in the format directive. Alternatively, `%V` could be used to
-  distinguish the two.
-
-  `inspect` output is not defined, however. This may be problematic if using
-  this code on other platforms (and expecting interoperability). To my
-  knowledge, no suitable specification of object representation aside from JSON
-  and `toString` exist. ( Aside: see "[Common object formats][3]" in the
-  "Console Living Standard" which basically says "do whatever" )
-
-- `%j` verb. This is an extension particular to this implementation. Currently
-  not very sophisticated, it just runs `JSON.stringify` on the argument.
-  Consider possible modifier flags, etc.
-
-- `<` verb. This is an extension that assumes the argument is an array and will
-  format each element according to the format (surrounded by [] and separated by
-  comma) (`<` Mnemonic: pull each element out of array)
-
-- how to deal with more newfangled JavaScript features (generic Iterables, Map
-  and Set types, typed Arrays, ...)
-
-- the implementation is fairly rough around the edges:
-
-- currently contains little in the way of checking for correctness. Conceivably,
-  there will be a 'strict' form, e.g. that ensures only Number-ish arguments are
-  passed to %f flags.
-
-- assembles output using string concatenation instead of utilizing buffers or
-  other optimizations. It would be nice to have printf / sprintf / fprintf (etc)
-  all in one.
-
-- float formatting is handled by toString() and to `toExponential` along with a
-  mess of Regexp. Would be nice to use fancy match.
-
-- some flags that are potentially applicable ( POSIX long and unsigned modifiers
-  are not likely useful) are missing, namely %q (print quoted), %U (unicode
-  format)
-
-# printf: prints formatted output
-
-sprintf converts and formats a variable number of arguments as is specified by a
-`format string`. In it's basic form, a format string may just be a literal. In
-case arguments are meant to be formatted, a `directive` is contained in the
-format string, preceded by a '%' character:
-
-    %<verb>
-
-E.g. the verb `s` indicates the directive should be replaced by the string
-representation of the argument in the corresponding position of the argument
-list. E.g.:
-
-    Hello %s!
-
-applied to the arguments "World" yields "Hello World!".
-
-The meaning of the format string is modelled after [POSIX][1] format strings as
-well as well as [Golang format strings][2]. Both contain elements specific to
-the respective programming language that don't apply to JavaScript, so they can
-not be fully supported. Furthermore we implement some functionality that is
-specific to JS.
-
-## Verbs
-
-The following verbs are supported:
-
-| Verb  | Meaning                                                        |
-| ----- | -------------------------------------------------------------- |
-| `%`   | print a literal percent                                        |
-| `t`   | evaluate arg as boolean, print `true` or `false`               |
-| `b`   | eval as number, print binary                                   |
-| `c`   | eval as number, print character corresponding to the codePoint |
-| `o`   | eval as number, print octal                                    |
-| `x X` | print as hex (ff FF), treat string as list of bytes            |
-| `e E` | print number in scientific/exponent format 1.123123e+01        |
-| `f F` | print number as float with decimal point and no exponent       |
-| `g G` | use %e %E or %f %F depending on size of argument               |
-| `s`   | interpolate string                                             |
-| `T`   | type of arg, as returned by `typeof`                           |
-| `v`   | value of argument in 'default' format (see below)              |
-| `j`   | argument as formatted by `JSON.stringify`                      |
-
-## Width and Precision
-
-Verbs may be modified by providing them with width and precision, either or both
-may be omitted:
-
-    %9f    width 9, default precision
-    %.9f   default width, precision 9
-    %8.9f  width 8, precision 9
-    %8.f   width 9, precision 0
-
-In general, 'width' describes the minimum length of the output, while
-'precision' limits the output.
-
-| verb      | precision                                                       |
-| --------- | --------------------------------------------------------------- |
-| `t`       | n/a                                                             |
-| `b c o`   | n/a                                                             |
-| `x X`     | n/a for number, strings are truncated to p bytes(!)             |
-| `e E f F` | number of places after decimal, default 6                       |
-| `g G`     | set maximum number of digits                                    |
-| `s`       | truncate input                                                  |
-| `T`       | truncate                                                        |
-| `v`       | truncate, or depth if used with # see "'default' format", below |
-| `j`       | n/a                                                             |
-
-Numerical values for width and precision can be substituted for the `*` char, in
-which case the values are obtained from the next args, e.g.:
-
-    sprintf("%*.*f", 9, 8, 456.0)
-
-is equivalent to:
-
-    sprintf("%9.8f", 456.0)
-
-## Flags
-
-The effects of the verb may be further influenced by using flags to modify the
-directive:
-
-| Flag  | Verb      | Meaning                                                                    |
-| ----- | --------- | -------------------------------------------------------------------------- |
-| `+`   | numeric   | always print sign                                                          |
-| `-`   | all       | pad to the right (left justify)                                            |
-| `#`   |           | alternate format                                                           |
-| `#`   | `b o x X` | prefix with `0b 0 0x`                                                      |
-| `#`   | `g G`     | don't remove trailing zeros                                                |
-| `#`   | `v`       | ues output of `inspect` instead of `toString`                              |
-| `' '` |           | space character                                                            |
-| `' '` | `x X`     | leave spaces between bytes when printing string                            |
-| `' '` | `d`       | insert space for missing `+` sign character                                |
-| `0`   | all       | pad with zero, `-` takes precedence, sign is appended in front of padding  |
-| `<`   | all       | format elements of the passed array according to the directive (extension) |
-
-## 'default' format
-
-The default format used by `%v` is the result of calling `toString()` on the
-relevant argument. If the `#` flags is used, the result of calling `inspect()`
-is interpolated. In this case, the precision, if set is passed to `inspect()` as
-the 'depth' config parameter.
-
-## Positional arguments
-
-Arguments do not need to be consumed in the order they are provided and may be
-consumed more than once. E.g.:
-
-    sprintf("%[2]s %[1]s", "World", "Hello")
-
-returns "Hello World". The presence of a positional indicator resets the arg
-counter allowing args to be reused:
-
-    sprintf("dec[%d]=%d hex[%[1]d]=%x oct[%[1]d]=%#o %s", 1, 255, "Third")
-
-returns `dec[1]=255 hex[1]=0xff oct[1]=0377 Third`
-
-Width and precision my also use positionals:
-
-    "%[2]*.[1]*d", 1, 2
-
-This follows the golang conventions and not POSIX.
-
-## Errors
-
-The following errors are handled:
-
-Incorrect verb:
-
-    S("%h", "") %!(BAD VERB 'h')
-
-Too few arguments:
-
-    S("%d") %!(MISSING 'd')"
-
-# Colors
-
-Adds functions used for displaying colored text.
-
-## Usage
-
-```typescript
-import {
-  bgBlue,
-  bgRgb24,
-  bgRgb8,
-  bold,
-  italic,
-  red,
-  rgb24,
-  rgb8,
-} from "https://deno.land/std@$STD_VERSION/fmt/colors.ts";
-
-console.log(bgBlue(italic(red(bold("Hello, World!")))));
-
-// also supports 8bit colors
-
-console.log(rgb8("Hello, World!", 42));
-
-console.log(bgRgb8("Hello, World!", 42));
-
-// and 24bit rgb
-
-console.log(rgb24("Hello, World!", {
-  r: 41,
-  g: 42,
-  b: 43,
-}));
-
-console.log(bgRgb24("Hello, World!", {
-  r: 41,
-  g: 42,
-  b: 43,
-}));
-```
