After landing #3358 the benchmarks exploded indicating problems with workers and deno_core_http_bench.

This PR dramatically fixes thread/syscall count that showed up on benchmarks. Thread count is not back to previous levels but difference went from hundreds/thousands to about ~50.

Removes three CI jobs

- Make assertThrows() return the Error
- Remove WalkOptions::onError()

- removes global `RESOURCE_TABLE` - resource tables are now created per `Worker`
  in `State`
- renames `CliResource` to `StreamResource` and moves all logic related
  to it to `cli/ops/io.rs`
- removes `cli/resources.rs`
- adds `state` argument to `op_read` and `op_write` and consequently adds
  `stateful_minimal_op` to `State`
- IMPORTANT NOTE: workers don't have access to process stdio - this is
  caused by fact that dropping worker would close stdout for process
  (because it's constructed from raw handle, which closes underlying file
  descriptor on drop)

* loader: support .wasm imports

* http_server: true

* Support named exports

* Clippy

This patch does not work with the recent bundler changes (#3325).
Unfortunately I didn't merge master before landing this patch. It has
something to do with console.log not working inside the compiler worker.

This reverts commit fd62379e.

Using an editor, such as VSCode, some of the plugins require some
files locally to provide a good editing experience.  These were
removed from the repo, but allowing people to add them back locally
but ensure they don't end up committed by accident would be helpful.

Re-enable flaky tests

Mistakenly re-enabled in #3275.

and update to prettier 1.19

Also, update `assert()` and remove not null assertions where possibly
in `cli`.

Closes #3273

- Bundles are fully standalone. They now include the shared loader with
  `deno_typescript`.
- Refactor of the loader in `deno_typescript` to perform module
  instantiation in a more
- Change of behaviour when an output file is not specified on the CLI.
  Previously a default name was determined and the bundle written to that
  file, now the bundle will be sent to `stdout`.
- Refactors in the TypeScript compiler to be able to support the concept
  of a request type.  This provides a cleaner abstraction and makes it
  easier to support things like single module transpiles to the userland.
- Remove a "dangerous" circular dependency between `os.ts` and `deno.ts`,
  and define `pid` and `noColor` in a better way.
- Don't bind early to `console` in `repl.ts`.
- Add an integration test for generating a bundle.

std/http/server.ts: Use listener.next() instead of listener.accept()

This test was improved in #3185.
