This is a partial fork of the windows iomgr code - specifically the IOCP and Socket pieces - with some improved architecture and encapsulation. And the start of a WindowsEventEngine.
Once this code is used in a gRPC TCP context, I imagine a few issues will shake out. Also, getting sanitizers set up with MSVC will take a bit of work (see a commit referencing abseil and MSVC bugs to hack around).
I forked the IomgrEventEngine's posix poller interfaces in the hope of negotiating compatibility between the platforms, but the interfaces diverged a fair bit, and I'm doubtful we'll be able to use these "pollers" generically in the same TCP code. Reunification might not happen, and that's probably fine, we'll see how similar the TCP code looks once it's fleshed out.
I also extracted the IomgrEventEngine's timer piece into a separate component, usable by both engines.

* Rename ResolveName to LookupHostname (same as EventEngine)
* Add stubs and no-op impls for LookupTXT and LookupSRV
* add native resolver tests that assert unimplemented
* extract custom name_server-setting logic and remove goto
* Separate SRV queries from grpc_dns_lookup_ares
* add necessary fixits before merging
* Automated change: Fix sanity tests
* fix missing ExecCtx on resolver tests
* separate out TXT lookup from hostname lookup (now all 3 are separate)
* rm DNS and update docs
* fix the fixer (forgot to add deps to BUILD)
* remove unused SRV and TXT args from ares hostname lookup method

* use max_frame_size to control encrypted frame sizes on the sender
* Add a flag to control usage of min_progress_size in TCP for receive buffer allocation
* revert changes to secure_endpoint and move them over to another PR
* add min_progress_size to tcp_posix_test

The pollset was not being properly shutdown. ASAN was failing 100% on
resolve_address_using_ares_resolver_test for a month (not identified in
CI).
* DoNothgin -> nullptr
This code is not compiled by default and has fallen out of sync with the
rest of the codebase. There's a good chance it won't be used, given our
current work to use an iomgr-drive EventEngine instead.
This code will continue to live in git history, should we need to bring
pieces of it back.
DNS requests were previously cancellable, but it was assumed
that the resolution callback would be called in all cases. Now, requests
provide a `bool Cancel(TaskHandle handle)` method that lets callers know
whether cancellation is successful, and if so, the callback will not be
run.
This is in accordance with EventEngine's cancellation semantics, and it
is a step towards migration from iomgr to EventEngine.

either product.
