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.

-## Methods
-
-### parse
-
-Takes an input `string` and a `formatString` to parse to a `date`.
-
-```ts
-import { parse } from 'https://deno.land/std@$STD_VERSION/datetime/mod.ts'
-
-parse("20-01-2019", "dd-MM-yyyy") // output : new Date(2019, 0, 20)
-parse("2019-01-20", "yyyy-MM-dd") // output : new Date(2019, 0, 20)
-parse("20.01.2019", "dd.MM.yyyy") // output : new Date(2019, 0, 20)
-parse("01-20-2019 16:34", "MM-dd-yyyy HH:mm") // output : new Date(2019, 0, 20, 16, 34)
-parse("01-20-2019 04:34 PM", "MM-dd-yyyy hh:mm a") // output : new Date(2019, 0, 20, 16, 34)
-parse("16:34 01-20-2019", "HH:mm MM-dd-yyyy") // output : new Date(2019, 0, 20, 16, 34)
-parse("01-20-2019 16:34:23.123", "MM-dd-yyyy HH:mm:ss.SSS") // output : new Date(2019, 0, 20, 16, 34, 23, 123)
-...
-```
-
-### format
-
-Takes an input `date` and a `formatString` to format to a `string`.
-
-```ts
-import { format } from "https://deno.land/std@$STD_VERSION/datetime/mod.ts";
-
-format(new Date(2019, 0, 20), "dd-MM-yyyy"); // output : "20-01-2019"
-format(new Date(2019, 0, 20), "yyyy-MM-dd"); // output : "2019-01-20"
-format(new Date(2019, 0, 20), "dd.MM.yyyy"); // output : "2019-01-20"
-format(new Date(2019, 0, 20, 16, 34), "MM-dd-yyyy HH:mm"); // output : "01-20-2019 16:34"
-format(new Date(2019, 0, 20, 16, 34), "MM-dd-yyyy hh:mm a"); // output : "01-20-2019 04:34 PM"
-format(new Date(2019, 0, 20, 16, 34), "HH:mm MM-dd-yyyy"); // output : "16:34 01-20-2019"
-format(new Date(2019, 0, 20, 16, 34, 23, 123), "MM-dd-yyyy HH:mm:ss.SSS"); // output : "01-20-2019 16:34:23.123"
-format(new Date(2019, 0, 20), "'today:' yyyy-MM-dd"); // output : "today: 2019-01-20"
