refactor: rewrite tests in std/ to use Deno.test

[bartlomieju]

• rewrite all tests in "std/" to use "Deno.test()"
• remove "std/testing/mod.ts"

LGTM - I love these big numbers of lines removed.

Please be extra sure this isn't silently breaking tests in std and cli/js. (If you change an assert there they should still break cargo test)

Confirmed, that adding failing assertion breaks cargo test

I asked about it on Gitter too (once I get an answer there I'll leave it here for posterity as well) but this change broke my CI. https://github.com/galkowskit/denofun/pull/43/checks?check_run_id=439140417

It looks like removal of mod.ts wasn't an issue for local tests (cached?) but it 404'd on CI. I need to update my tests to Deno.test, that's for sure.

But what would be the recommended approach for community to lock dependencies and update them later? import { assertEquals, test } from "https://deno.land/std/testing/mod.ts@<commit-hash>"? Would that even work for removed files?

import { assertEquals, test } from "https://deno.land/[email protected]/testing/mod.ts

There are some references to std/testing/mod.ts in the manual and the README.
