gRPC is currently getting formatted with two different clang-format implementations, and due to some weirdness they have different include file orderings. This change introduces clang-format configuration to ensure that the two systems align - it's *highly* expected that this will need some maintenance going forward as the two systems evolve.
Closes#40905

See `grpc_check.h`. This code redefines the abseil `CHECK*` macros using custom gRPC macros when building tests. In `bazel test ...` builds, on check failure, `PostMortemEmit()` will dump state to the log before crashing.
Caveat: to prevent circular dependencies, code that `postmortem` relies on cannot use the custom gRPC CHECK macros. This is not much code, ~50 source files. grep for the `absl/log:check` bazel dependency.

At the same time, makes the change to elevate channelz to a first class thing a transport should provide.
We still (for the moment) allow a transport to return a null SocketNode, but the transport must explicitly opt to do so.
In turn, update subchannel, server code to use the transport API to retrieve this object, instead of using an alternative squirrly method that's different between client, server.

Specifically:
- use `OrphanablePtr<>` for `grpc_endpoint`
- use `absl::AnyInvocable<>` instead of `grpc_closure`
- use `EventEngine::Run()` instead of `ExecCtx::Run()`
- use `SliceBuffer` instead of `grpc_slice_buffer`
- use `absl::Status` instead of `grpc_error_handle`
- use `absl::string_view` instead of `const char*` for handshaker names
Also pass acceptor via `HandshakerArgs` instead of as a separate parameter.
Also changed chttp2 and httpcli to use `OrphanablePtr<>` for the endpoint.

This gives grpc_endpoint the same destruction-is-shutdown semantic as
EventEngine::Endpoint, which will make the migration easier.

[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.

With 1k iterations instead of 10k iterations, this test takes ~90s in the RBE environment. There must have been a regression somewhere, since this test did not used to fail every time.

[grpc][Gpr_To_Absl_Logging] Migrating from gpr to absl logging - BUILD
In this CL we are just editing the build and bzl files to add dependencies.
This is done to prevent merge conflict and constantly having to re-make the make files using generate_projects.sh for each set of changes.

[grpc][Gpr_To_Absl_Logging] Migrating from gpr to absl logging GPR_ASSERT
Replacing GPR_ASSERT with absl CHECK
These changes have been made using string replacement and regex.
Will not be replacing all instances of CHECK with CHECK_EQ , CHECK_NE etc because there are too many callsites. Only ones which are doable using very simple regex with least chance of failure will be replaced.
Given that we have 5000+ instances of GPR_ASSERT to edit, Doing it manually is too much work for both the author and reviewer.

This adds the following new targets:
- `channel`: A virtual interface for a channel.
- `legacy_channel`: A channel implementation that supports the filter stack and call v2.
- `channel_create`: A standalone function to create a channel.
- `server_interface`: A base class with a few accessor methods used in surface/call.cc.
- `server`: The actual server implementation.
- `api_trace`, `call_tracer`, `server_call_tracer_filter`, `call_finalization`: These were split out of `grpc_base` to avoid various dependency problems.
- `compression`: This is a combination of the previously existing `compression_internal` target and the compression code that was part of `grpc_base`.

Fixing TSAN data races of the kind -
https://source.cloud.google.com/results/invocations/c3f02253-0d0b-44e6-917d-07e4bc0d3d62/targets/%2F%2Ftest%2Fcpp%2Fperformance:writes_per_rpc_test@poller%3Dpoll/log
I think the original issue was the non-atomic load in
writes_per_rpc_test.cc but also making the change to use barriers
instead of relaxed atomics (probably unimportant but I'll prefer safety
in the absence of otherwise comments).
Could probably also use std::atomic but feeling a bit lazy to make the
changes throughout.

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.
