Closes#36396
COPYBARA_INTEGRATE_REVIEW=https://github.com/grpc/grpc/pull/36396 from yijiem:xds-cluster-end2end-test-twin 26062ea1b4
PiperOrigin-RevId: 626207011
Currently channel filter construction returns a `StatusOr<T>`, this change makes it return a `StatusOr<P<T>>` where P is `unique_ptr`, `OrphanablePtr`, `RefCountedPtr`, `DualRefCountedPtr`, etc (most of the code really doesn't need to know, so I'm choosing to leave the flexibility).
That smart pointer is then stored in the channel stack instance, and dereferenced when needed.
This means that channel filters no longer need to be movable (which is a nice simplification), and puts these level-1 filters on a similar memory management track as the level-2 filters we have planned.
(this change also converts client load reporting to v3 apis -- it's a bit accidentally picked up, but seems ok to pull through too)

To simplify the build process, let's remove unnecessary Bazel bindings. These bindings were originally used to manage differences between OSS and our internal build environment. However, bindings are now deprecated and introduce unnecessary complexity. Removing them will make the build process more straightforward and easier to maintain.

Forked from #35957
This PR refactors the credentials types to remove Secure and Insecure Channel and Call credentials types. We standardize on a `c_creds()` accessor method for all credentials types, which can now be treated uniformly. This notably removes special-case handling of insecure credentials.
The special code-paths for insecure creds are no longer necessary in the wake of #25586.

This removes two Executor::Run dependencies, and requires that all ServerCallbackCall implementations implement the new `RunAsync` method. There's one other known other implementation of ServerCallbackCall that will need to be updated.
We could also support an "inefficient" path that uses the default engine (not implemented here), for all subclasses that do not want to update. As far as anyone is aware, the ServerCallbackCall class was never intended to be subclassed externally.

Adding testing for `Size()` on `MeshLabelsIterable` as promised on https://github.com/grpc/grpc/pull/35371
This method doesn't get used the OTel C++ library at present so it was untested earlier, and bugs in its implementation were noticed later. To avoid that issue in the future, adding manual testing of this method.
Changes -
* Moved `MeshLabelsIterable` to the header to be able to test its Size method directly. Also had to move around some internals to be able to do so.
* Replaced `absl::variant<grpc_core::Slice, StructPb> metadata_` from decoding the metadata lazily to just decoding it in the constructor. I don't remember the original thinking behind this. Maybe I wanted the decoding to happen lazily, but there doesn't seem to be much gain from doing it lazily, we instead have to deal with the overhead of `variant`.

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_base` BUILD target:
- channelz

- call_combiner

- iomgr

PiperOrigin-RevId: 608680098
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.
