[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.

Refines the test in the fuzzer to only check input == output if the frame was re-encodable.
Also tweaks some hpack encoder stuff to not crash but simply report errors where appropriate.

gRPC shutdown may happen asynchronously with `work_serializer_dispatch`, so wait briefly until shutdown completes in the child's post-fork.

[Gpr_To_Absl_Logging] Removing instances of gpr_should_log and replacing it with ABSL_VLOG_IS_ON.
gpr_should_log function will be deleted soon.
**VLOG(2)** is equivalent to gpr_log(**GPR_DEBUG**, ... )
We are replacing two instances of **gpr_log(GPR_INFO**, ... ) with **VLOG(2)** because this code appears to be slightly expensive.
I can also continue to use LOG(INFO) and check current settings using absl::MinLogLevel() . Would you want me to do that?

[Gpr_To_Absl_Logging] Migrating from gpr to absl logging - gpr_set_log_function
Adding a warning for users of gpr_set_log_function.
This function will be deleted soon.
https://github.com/grpc/proposal/pull/425
Other options considered ( and discarded )
1. Using DFATAL instead of ERROR. Discarded this because we still have one critical unit test to clean up before we delete gpr_set_log_function. This test will fail if we use DFATAL. EXPECT_DFATAL macro is not available to be used.
2. Considered making a new absl log sink , and then that log sink should have a function pointer with the same signature as gpr_log_func. This function pointer can be set from gpr_set_log_function. However if this custom function uses absl from within it, that will cause infinite recursion. Made me drop the idea.

All TraceFlags are now configured in `src/core/lib/debug/trace_flags.yaml`. The format is:
```
my_flag:
default: false # the default value; default=false
description: Some Description
debug_only: false # debug_only flags only work in debug builds; default=false
internal: false # internal flags will not show up in documentation; default=false
```
To regenerate the trace flag source code, run `tools/codegen/core/gen_trace_flags.py` (requires mako). This script is also run when sanity checking.
This PR also adds two new features:
### Glob-based flag configuration
Trace flag configuration now supports `?` (single wildcard character) and `*` (one or more wildcard characters). For example, using `GRPC_TRACE='event_engine*'` will enable all flags that match that glob. It expands to:
* event_engine
* event_engine_client_channel_resolver
* event_engine_dns
* event_engine_endpoint
* event_engine_endpoint_data
* event_engine_poller
### A cleaner trace-logging macro in abseil logging format
If your goal is only to add log statements when the `fault_injection_filter` trace flag is enabled, you can use the macro:
```
GRPC_TRACE_LOG(fault_injection, INFO) << "Filtered:" << 42;
```
When the trace flag is enabled, the the log will show something like this:
```
I0000 00:00:1715733657.430042 16 file.cc:174] Filtered:42
```
----
Note: just like with the gpr_log to abseil logging conversion, the pre-existing trace logging usages can be replaced with the new tracing macro across multiple PRs.
