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:
```

BM_Pick/weighted_round_robin/100000 148 ns 148 ns 9882
```
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_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.

PiperOrigin-RevId: 658181731
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.

[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.
Closes#36879

This breaks the following pieces out of the `grpc_client_channel` BUILD target:
- backend_metric_parser
- oob_backend_metric
- child_policy_handler
- backup_poller
- service_config_channel_arg_filter
- client_channel_channelz
- client_channel_internal_header
- subchannel_connector
- subchannel_pool_interface
- config_selector
- client_channel_service_config_parser
- retry_service_config_parser
- retry_throttle
The code left in the `grpc_client_channel` target will need more work to pull apart.
