Implement DNS using dns service for iOS.
Current limitation:
1. Using a custom name server is not supported.
2. Only supports `LookupHostname`. `LookupSRV` and `LookupTXT` are not
implemented.
3. Not tested with single stack (ipv4 or ipv6) environment
4. ~Not tested with multiple ip records per stack~ manually tested with
wsj.com
5. Not tested with multiple interface environment
Need the ability to override server-side keepalive permit without calls
default without affecting client-side settings.

Normally, c-ares related fds are destroyed after all DNS resolution is
finished in [this code
path](c82d31677a/src/core/ext/filters/client_channel/resolver/dns/c_ares/grpc_ares_wrapper.cc (L210)).
Also there are some fds that c-ares may fail to open or write to
initially, and c-ares will close them internally before grpc ever knows
about them.
But if:
1) c-ares opens a socket and successfully writes a request on it
2) then a subsequent read fails
Then c-ares will close the fd in [this code
path](bad62225b7/src/lib/ares_process.c (L740)),
but gRPC will have a reference on the fd and will still use it
afterwards.
Fix here is to leverage the c-ares socket-override API to properly track
fd ownership between c-ares and grpc.

Over the past 5 days, this experiment has not introduced any new flakes,
nor increased any flake rates. Let's enable it for debug builds. To
prevent issues over the weekend, I plan to merge it next week, July 31st
(with announcement).
This adds a new GKE benchmark job, which runs the set of "dashboard"
scenarios for every gRPC experiment configured in the script. Results
are published to BigQuery at
`e2e_benchmarks.ci_cxx_experiment_results_${N}core.${experiment}`
See https://github.com/grpc/grpc/pull/33907 for the scenario config.
This PR fixes the bootstrap generator interop test by making the node
metadata flag dependent on version, which was causing a breakage
previously as all bootstrap generator version's don't necessarily
support the deexpiermentalized flag.
- Make `Value` a simple wrapper around `Pointer` and use some blessed
vtables to distinguish strings vs ints vs actual pointers - this saves 8
bytes per value stored
- introduce `RcString` as a lightweight container around an immutable
string - this saves some bytes vs the shared_ptr<std::string> approach
we previously had, and importantly opens up the technique (via
`RcStringValue`) to channel node keys also, which should increase
sharing and consequently also decrease total memory usage

Refactored OpenCensus context propagation flow, now propagation happens
for each call and context will be automatically propagated from gRPC
server to gRPC client.
We're using `execution_context` in OpenCensus since the context is
related to OpenCensus and it helps wrap `contextVar` for us.
### Testing
* Added a new Bazel test case for context propagation.

This PR covers C++ only. Other language owners: feel free to ping me if
this would be useful for you.
This allows scenario_config to produce a small superset of tests
required to generate the performance dashboard
https://grafana-dot-grpc-testing.appspot.com/. This only adds a category
to some existing scenarios, and to my knowledge, should not affect any
current automation that uses scenario_config.
I plan to use this category to run gRPC-core experiments and produce
equivalent dashboards. It seems worth landing this independently of
those job configurations, but I'm flexible.

Inserts and removals create `O(log(n))` new nodes with a persistent AVL
- which is nice - but if there's ultimately no mutation even this is
wasteful. Do some extra work in channel args to verify that there is
indeed a mutation, otherwise continue to share the same underlying
object.
Reduces node size from 112 bytes to 88 bytes on x64 opt builds.
(also delete the unused specialization of `AVL<T, void>`)

The most important change here is to setting `resource_suffix` and
`server_xds_port` flags to "generate randomly" by default. Previously we
were suggesting static values, and devs ended up with resource conflict
errors.

Fix: #33643.
This change adds `__reduce__` to `AioRpcError` to allow pickle.
### Testing
Added bazel unit test, without this change, test will fail with error:
```
TypeError: AioRpcError.__init__() missing 3 required positional arguments: 'code', 'initial_metadata', and 'trailing_metadata'
```
CNR a WindowsEventEngine listener flake in:
* 10k local Windows development machine runs
* 50k Windows RBE runs
* 10k Windows VM runs
It fails ~5 times per day on the master CI jobs.
This PR adds some logging to try to see if an edge is missed, and
switches the thread pool implementation to see if that makes the flake
go away. If the flakes disappear, I'll try removing one or the other to
see if either independently fix the problem (hopefully not logging).

Reverts grpc/grpc#33819
Verified that it passed these jobs:
`grpc/core/master/linux/grpc_basictests_c_cpp_dbg`
`grpc/core/master/linux/grpc_basictests_c_cpp_opt`
`grpc/core/master/linux/grpc_portability`
Resolves a set of failures seen rolling out promises - we need to read
all of the incoming payload before doing request matching.

Why: Cleanup for chttp2_transport ahead of promise conversion - lots of
logic has become interleaved throughout chttp2, so some effort to
isolate logic out is warranted ahead of that conversion.
What: Split configuration and policy tracking for each of ping rate
throttling and abuse detection into their own modules. Add tests for
them.
Incidentally: Split channel args into their own header so that we can
split the policy stuff into separate build targets.

This is so that the newly added dns_test (which uses twisted-based
server) within the posix_event_engine_test can run on those platforms.

This PR:
- Fixes the xds-protos Python package, which was broken when the `udpa`
submodule was removed
- This required re-adding the protoc-gen-validate submodule
- Adds non-Bazel tests for xds-protos and all of its dependent packages
- Versions xds-protos the same way as the rest of the Python packages
- Fixes Python 3.11 support in `run_tests.py`, which is necessary for
the testing mentioned above
CC @sergiitk You won't be able to consume this in the interop tests
until it makes it into a release. I'm thinking I'll want to backport
this to the 1.57.x branch to make that happen faster.
CC @drfloob to inform him about the likely backport.
- add check that there are no unwanted .current_version files left in
the repo after foobar/Dockerfile gets deleted.
- revisit the logic for repo digest vs id digest of docker images.
This is a clean up PR for discussion in #33257.
