This PR aims to de-experimentalize the APIs for GCP Observability.
We would have ideally wanted public feedback before declaring the APIs
stable, but we need stable APIs for GA.
Changes made after API review with @markdroth@veblush, @ctiller and the
entire Core/C++ team -
* The old experimental APIs `grpc::experimental::GcpObservabilityInit`
and `grpc::experimental::GcpObservabilityClose` are now deprecated and
will be deleted after v.1.55 release.
* The new API gets rid of the Close method and follows the RAII idiom
with a single `grpc::GcpObservability::Init()` call that returns an
`GcpObservability` object, the lifetime of which controls when
observability data is flushed.
* The `GcpObservability` class could in the future add more methods. For
example, a debug method that shows the current configuration.
* Document that GcpObservability initialization and flushing (on
`GcpObservability` destruction) are blocking calls.
* Document that gRPC is still usable if GcpObservability initialization
failed. (Added a test to prove the same).
* Since we don't have a good way to flush stats and tracing with
OpenCensus, the examples required users to sleep for 25 seconds. This
sleep is now part of `GcpObservability` destruction.
Additional Implementation details -
* `GcpObservability::Init` is now marked with `GRPC_MUST_USE_RESULT` to
make sure that the results are used. We ideally want users to store it,
but this is better than nothing.
* Added a note on GCP Observability lifetime guarantees.

Fix python type hints for async iteration on `UnaryStreamCall` and
`StreamStreamCall`. Those classes _are_ `AsyncIterable`s and `__aiter__`
returns an `AsyncIterator`.

Followup for https://github.com/grpc/grpc/pull/32649 (which disabled the
tests mentioned below).
Also sets correct path for tests build by ninja on windows, so that they
don't get skipped.
Once merged, I'll backport to 1.54.x and 1.53.x
The original issue with tests being skipped.

This is a prerequisite for upgrading to protobuf 22.x
(upb and protobuf now depend on utf8_range)
Currently utf8_range isn't referenced by anything, but it's better to
bring the subtree in advance to make the protobuf upgrade PR smaller.

Notes:
- `+trace` fixtures haven't run since 2016, so they're disabled for now
(7ad2d0b463 (diff-780fce7267c34170c1d0ea15cc9f65a7f4b79fefe955d185c44e8b3251cf9e38R76))
- all current fixtures define `FEATURE_MASK_SUPPORTS_AUTHORITY_HEADER`
and hence `authority_not_supported` has not been run in years - deleted
- bad_hostname similarly hasn't been triggered in a long while, so
deleted
- load_reporting_hook has never been enabled, so deleted
(f23fb4cf31/test/core/end2end/generate_tests.bzl (L145-L148))
- filter_latency & filter_status_code rely on global variables and so
don't convert particularly cleanly - and their value seems marginal, so
deleted

When using this internally, we noticed that it's impossible to use
custom_metadata.h without creating a dependency cycle between
:custom_metadata and :grpc_base.
A full build refactoring is too large right now, so merge that header
into :grpc_base for the time being.
Also, separate `SimpleSliceBasedMetadata` into its own file, so that it
can be reused in custom_metadata.h.

Fixes b/276092199. Stanley noticed that EnvironmentDetection requests
were timing out, so increasing the deadline.

This PR also centralizes the client channel resolver selection. Resolver
selection is still done using the plugin system, but when the Ares and
native client channel resolvers go away, we can consider bootstrapping
this differently.
This commit adds support for using CIDR blocks defined in the `no_proxy`
environment variable. For example:
```
http_proxy=http://localhost:8080 no_proxy=10.10.0.0/24
```
The example above would bypass the proxy if the server IP matched
10.10.0.0 - 10.10.0.255.
Closes#22681

Perf shows that the memory are accessed twice for call->wrapped in
startBatch. If we assign call->wrapped to a variable and then use it in
startBatch, only one memory access is needed. Then, the second
attempting to get the value of call->wrapped will be done via register.

Fix-forward for https://github.com/grpc/grpc/pull/32629. Referencing the
[documentation](https://github.com/marketplace/actions/labeler), if the
top-level list for a label is a list of strings, it is treated as a
single `any` entry. `any` entries are ANDed together. This means that
the original PR said "label lang/python if anything _besides_
grpc_core_dependencies.py changed." This is obviously not desired.
This PR makes the `any` explicit. The logic now says "label lang/python
if any of these few files has changed OR if any file but
grpc_core_dependencies.py under src/python has changed."
I'm still not 100% certain that this will work, but the stakes aren't
super high.
