Changes -
* Add CMake build support to `grpcpp_otel_plugin`. Currently, we are only supporting the `find_package CONFIG` method for depending on `opentelemetry-cpp`.
* Since, `grpcpp_otel_plugin` is an extension of gRPC, it will not be built by default. To enable building of this target, a new CMake option `gRPC_BUILD_GRPCPP_OTEL_PLUGIN` is being added.
* Also add `CMakeLists.txt` to the otel example.
The `otel_plugin_test` can also be built through cmake but, for the CI to work, there are some additional changes. Those will be made in an upcoming PR.

While we're here, also change the Echo service handler to mutate clients before handling the RPC, mainly so that it can be reasoned about in cases involving client cancellation.

There are tests in another change I'm working on for which we need to do things like:
1) waiting for N RPCs to concurrently pile up on a server
2) doing 1) multiple times sequentially on the same server

also:
- remove tail recursion from promise endpoint read completion (actually overflowed stack!)
- remove retry filter from benchmark - we probably don't want this long term, but for now nobody else is using this benchmark and our use case doesn't use grpc retries so.... good enough

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`.

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.

As discussed, this change adds scoping to `CsmObservability` such that when that object goes out of scope, new channels and servers don't record metrics. In the documentation, I've talked about how existing channels/servers are going to continue to record metrics but i've left room for us to change that behavior in the future.
The current way of doing this is through a global bool since there can only be one plugin right now, but we'll change this to use the global stats plugin registry in the future.

Changes -
* `CsmObservability` API will now use the `CsmOpenTelemetryPluginOption` internally. After this change, `CsmObservability` will enable observability for all channels and servers. (Earlier, `CsmObservability` only enabled observability for CSM-enabled channels and servers.) CSM labels will still be added just for CSM-enabled channels and servers.
* Also, we no longer need the ability to set `LabelInjector` on the `OpenTelemetryPluginBuilder` directly. Instead, we always use `PluginOption` to inject the `LabelInjector`. This simplifies the code as well.
Note that `SetTargetSelector` and `SetServerSelector` APIs on the `OpenTelemetryPluginBuilderImpl` are not being deleted yet since we might need them shortly. This is also why `OpenTelemetryPluginBuilderImpl` is not being deleted right now.

PiperOrigin-RevId: 604323898
When testing CSM Observability, we discovered that the c++ xds interop client is not sending any payload with the `UnaryCall` RPCs so most of the metrics will have a value of 0.
Adding a payload to the xds interop client here.
We need this fix so that we can verify that the metrics are recording the right number of bytes being sent / received. So we need a non-trivial payload to be sent with the `UnaryCall` RPC between the xds interop client and server.

Also, if zone and region are both specified, zone takes precedence.
