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.

-# Deno example programs
-
-This module contains small scripts that demonstrate use of Deno and its standard
-module.
-
-You can run these examples using just their URL or install the example as an
-executable script which references the URL. (Think of installing as creating a
-bookmark to a program.)

-Or
-
-```shell
-deno install --allow-net https://deno.land/std/examples/echo_server.ts
-```
-
-### cat - print file to standard output
