Towards simplifying (or better removing entirely) the CoreResource
trait. Resources should be any bit of privileged heap allocated memory
that needs to be referenced from JS, not very specific trait
implementations. Therefore CoreResource should be pushed towards being
as general as possible.

Max latency benchmark went to zero for deno_proxy.

* Split ThreadSafeState into State and GlobalState. State is a "local"
  state belonging to "Worker" while "GlobalState" is state shared by
  whole program.
* Update "Worker" and ops to use "GlobalState" where applicable
* Move and refactor "WorkerChannels" resource

Consolidates asserts#equal branches for keyed collections (Map/Set) and supports deep equality of Map keys  (#3258)

Use --lock-write=lock.json or --lock-check=lock.json on the command
line.

* Upgrade node_modules
* Simplify tagline
* Move gclient_config.py out of root
* Move package.json to tools
* Remove yarn.lock
* Remove CONTRIBUTING.md

This avoids a crash when the Deno process has been running for
2**32 ms (about 50 days). Additionaly, time complexity of finding which
timer is due to fire next is reduced from from O(n) to O(log n).

* Add sd-streams from https://github.com/stardazed/sd-streams/blob/master/packages/streams/src/

* change the interfaces in dom_types to match what sd-streams expects

Worth noting due to implementation of the Headers class the contents of headersMap have lowercase keys, although this matches the specification as header keys are case agnostic it does seem to not match behaviour of other implementations in other languages I have seen, would require some rewriting of Headers.ts
