This is a first pass implementation which is still missing several important
features:
- support for --inspect-brk (#4503)
- support for source maps (#4501)
- support for piping console.log to devtools console (#4502)

* rewrite test runner in Rust
* migrate "test" and "runTests" functions from std to "Deno" namespace
* use "Deno.test()" to run internal JS unit tests
* remove std downloads for Deno subcommands
* Use PathBuf for DenoSubcommand::Bundle's out_file
* Use PathBuf for DenoSubcommand::Format's files
* Use PathBuf for DenoSubcommand::Install's dir
* Use PathBuf for read/write whitelists
This flag was added to evaluate performance relative to tokio's threaded
runtime. Although it's faster in the HTTP benchmark, it's clear the runtime
is not the only perf problem.
Removing this flag will simplify further refactors, in particular
adopting the #[tokio::main] macro. This will be done in a follow up.
Ultimately we expect to move to the current thread runtime with Isolates
pinned to specific threads, but that will be a much larger refactor. The
--current-thread just complicates that effort.
- Remove ability to specify run arguments like `--allow-net` after the
script argument. It's too hacky to make work with clap.
- Remove `--v8-options`, instead use `--v8-flags=--help`
- Give more descriptive names to unit tests in flags.rs
- Assume argv and subcommand into DenoFlags struct so the output of
flags module is only DenoFlags rather than the tuple (subcommand, flags,
argv).
- Improve CLI help text
- Make `deno run` specific args like `--allow-net` only show up in 'deno
help run' instead of as global flags in `deno help`.
- Removes `deno version` to simplify our implementation and be closer to
clap defaults. `deno -V` now only shows Deno's version and not V8's nor
TypeScript. `Deno.versions` can be used to see that information.
- Prevent clap from auto-detecting terminal width and attempting to wrap
text.
