Fix for grpc_build_protobuf_at_head -> python_linux_opt_native_buildonly timeout
Found the following error during Python build:
When we mount and reuse the existing repo from host machine inside docker container, the `tools/bazel.rc` file is shared to the docker container and the Bazel override host location written to `tools/bazel.rc` from tools/.../grpc_build_submodule_at_head.sh (outside docker container) forces bazel to look for the same host location inside the docker container, which doesn't exist.
Hence overriding it again with the working directory inside the container should solve this issue.

Two new benchmarks here-in.
Benchmark 1: `bm_picker`
------
Measures various load balancing policies pick performance. For now we cover `pick_first` and `weighted_round_robin` at 1, 10, 100, 1000, 10000, and 100000 backends.
Today's output:
```

```
Benchmark 2: `bm_load_balanced_call_destination`
-----
This benchmark measures call performance when a call spine passes through a `LoadBalancedCallDestination`, and with `BM_LoadBalancedCallDestination` also the construction/destruction cost of this object.
We do not consider picker performance in this benchmark as it's separately covered by `bm_picker` above.
Today's output:
```

BM_UnaryWithSpawnPerEnd<UnstartedCallDestinationFixture<LoadBalancedCallDestinationTraits>> 1255 ns 1255 ns 1076

BM_LoadBalancedCallDestination 92.8 ns 92.8 ns 15063
```
Notes
------
There's some duplicated code between the benchmarks & tests -- this is ok -- as the tests evolve we'll likely want to add more checks to the fixtures, whereas as the benchmarks evolve we may well want to optimize the fixtures so that performance of the systems under test dominate more. That is, the duplicated code is expected to have different evolutionary tracks.

The Ruby artifact build is timing out at 1hr30m, specifically `build_artifact.ruby_native_gem_linux_aarch64-linux` in the `tools/internal_ci/linux/grpc_distribtests_ruby.sh` job. Most of the other Ruby builds take around 1hr15m, so the build time is increasing regardless.
@stanley-cheung this should probably be investigated. In the meantime, to hopefully unblock the v1.66 release, let's increase the build timeout.

The oldest gcc version that gRPC supports as of today is gcc 7 but gcc 7 has an issue with template supports that gRPC already picked up. Recently we managed to fix it in gRPC library code but we still have some in our test code. Given that it's not easy to fix since it requires many trial error approach to find a way to satisfy gcc 7 and eventually gcc 7 will be dropped from our supported compilers, let's have this mitigation where just main grpc++ target is being tested for gcc 7 so that users can use grpc with it without having to fix this hairy issue.

- add a benchmark for various metadata creation styles
- add factory functions for status + message - these are 3-10x faster than going via absl::Status
- add a `MakePooledForOverwrite` function to Arena, use it everywhere -- this naming matches `std::make_unique_for_overwrite` in C++20, and avoids some language mandated initialization in `Table` (underlying `MetadataMap<>`) - speeding creation of metadata handles by 30%
For `bm_call_spine` we see before:
```
BM_UnaryWithSpawnPerEnd<CallSpineFixture>_median 745 ns 745 ns
```
and after:
```
BM_UnaryWithSpawnPerEnd<CallSpineFixture>_median 699 ns 699 ns

[grpc][Gpr_To_Absl_Logging] Migrating from gpr to absl logging - gpr_log
In this CL we are migrating from gRPCs own gpr logging mechanism to absl logging mechanism. The intention is to deprecate gpr_log in the future.
We have the following mapping
1. gpr_log(GPR_INFO,...) -> LOG(INFO)
2. gpr_log(GPR_ERROR,...) -> LOG(ERROR)
3. gpr_log(GPR_DEBUG,...) -> VLOG(2)
Reviewers need to check :
1. If the above mapping is correct.
2. The content of the log is as before.
gpr_log format strings did not use string_view or std::string . absl LOG accepts these. So there will be some elimination of string_view and std::string related conversions. This is expected.

As we've learned what configuration is needed for our benchmarks the settings have been growing more and more bespoke for each binary. Try to consolidate that into some useful defaults.
Also ensure we always `linkstatic=1`. `cc_binary` defaults to this, so it's reasonable to assume that's the performance our customers see. It also deeply impacts performance for small microbenchmarks, and so enabling it gives us more apples:apples, and saves chasing things that don't matter.

Previously, metadata mutations were made by the picker directly, which meant that they would be applied even if the channel winds up discarding the pick due to the returned subchannel having been disconnected by the time the pick result is returned. This changes the API such that pickers return metadata mutations along with the pick result, so that the mutations won't get applied unless the pick result is actually used.

[Gpr_To_Absl_Logging] Cleaning up the allow list for deprecated functions.
This file has a list of deprecated functions.
Any new instance of a deprecated function being used in the code will be flagged by the script. If there is a new instance of a deprecated function in a Pull Request, then the Sanity tests will fail.
We are currently working on clearing out the usage of deprecated functions in our code base.
For that reason, while our cleaning is in progress we have a temporary allow list. The allow list has a list of files where clean up of deprecated functions is pending. As we clean up the deprecated function from files , we will remove them from the allow list.
Ideally, it would be wise to do the file clean up and the altering of the allow list int the same PR. This will make sure that any roll back of a clean up PR will alter the allow list and avoid build failures.
