This is a big rewrite of global config.
It does a few things, all somewhat intertwined:
1. centralize the list of configuration we have to a yaml file that can
be parsed, and code generated from it
2. add an initialization and a reset stage so that config vars can be
centrally accessed very quickly without the need for caching them
3. makes the syntax more C++ like (less macros!)
4. (optionally) adds absl flags to the OSS build
This first round of changes is intended to keep the system where it is
without major changes. We pick up absl flags to match internal code and
remove one point of deviation - but importantly continue to read from
the environment variables. In doing so we don't force absl flags on our
customers - it's possible to configure grpc without the flags - but
instead allow users that do use absl flags to configure grpc using that
mechanism. Importantly this lets internal customers configure grpc the
same everywhere.
Future changes along this path will be two-fold:
1. Move documentation generation into the code generation step, so that
within the source of truth yaml file we can find all documentation and
data about a configuration knob - eliminating the chance of forgetting
to document something in all the right places.
2. Provide fuzzing over configurations. Currently most config variables
get stashed in static constants across the codebase. To fuzz over these
we'd need a way to reset those cached values between fuzzing rounds,
something that is terrifically difficult right now, but with these
changes should simply be a reset on `ConfigVars`.

PR #32215 added the verified root cert subject to the lower level
`tsi_peer`. This PR is a companion to that and completes the feature by
bubbling the information up to the `TsiCustomVerificationCheckRequest`
which is part of the user facing API for implementing custom
verification callbacks.
Looks like this was accidentally dropped from our build files in
https://github.com/grpc/grpc/pull/21929, which means that this test
hasn't actually been built or run in almost 3 years. Unsurprisingly
after all that time, I had to make some changes to the test to get it to
actually build.

* A modest split of `:gpr` for mpscq support
A full split of the `gpr` target into 25 separate targets is building,
but there are some hurdles to get over with respect to ODR violations
and public API support for the gpr library.
This PR splits off a small chunk of that work.

* Rename the default EventEngine headers
Small cleanup. This code hasn't been related to factories for a month or
two.
* ensure only one target contains default_event_engine.h
* src + hdr in same target
* include guards
* Refactor end2end tests to exercise each EventEngine
* fix incorrect bazel_only exclusions
* Automated change: Fix sanity tests
* microbenchmark fix
* sanitize, fix iOS flub
* Automated change: Fix sanity tests
* iOS fix
* reviewer feedback
* first pass at excluding EventEngine test expansion
Also caught a few cases where we should not test pollers, but should
test all engines. And two cases where we likely shouldn't be testing
either product.
* end2end fuzzers to be fuzzed differently via EventEngine.
* sanitize
* reviewer feedback
* remove misleading comment
* reviewer feedback: comments
