Expand server promises to run with C++ end2end tests.
Across connected_channel/call/batch_builder/pipe/transport:
- fix a bug where read errors weren't propagated from transport to call
so that we can populate failed_before_recv_message for the c++ bindings
- ensure those errors are not, however, used to populate the returned
call status
Add a new latch call arg to lazily propagate the bound CQ for a server
call (and client call, but here it's used degenerately - it's always
populated). This allows server calls to be properly bound to
pollsets.(1)/(2)
In call.cc:
- move some profiling code from FilterStackCall to Call, and then use it
in PromiseBasedCall (this should be cleaned up with tracing work)
- implement GetServerAuthority
In server.cc:
- use an RAII pattern on `MatchResult` to avoid a bug whereby a tag
could be dropped if we cancel a request after it's been matched but
before it's published
- fix deadline export to ServerContext
In resource_quota_server.cc:
- fix some long standing flakes (that were finally obvious with the new
test code) - it's legal here to have client calls not arrive at the
server due to resource starvation, work through that (includes adding
expectations during a `Step` call, which required some small tweaks to
cq_verifier)
In the C++ end2end_test.cc:
- strengthen a flaky test so it passes consistently (it's likely we'll
revisit this with the fuzzing efforts to strengthen it into an actually
robust test)
(1) It's time to remove this concept
(2) Surprisingly the only test that *reliably* demonstrates this not
being done is time_change_test

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`.

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.

Based on a handful of https://abseil.io/tips, it's generally advised to
only fully-qualify namespaces when in a `using` statement, or when it's
otherwise required for compilation. In all other cases, the general
recommendation is to not fully-qualify.
This change fixes most `grpc.*` namespace uses. There are potential
challenges in trying to make blanket changes to non-gRPC namespace uses,
such as `::testing`, since there is also a `grpc::testing` namespace.
