The Oauth2 credentials currently rely on pollsets and polling entities, partially because grpc_core::HttpRequest relies on them as well. This is a temporary solution to get both iomgr and EventEngine clients to pass the oauth2 interop tests.
Tested with the client experiment on and off.

Fixes#33935
The gRPC spec is not clear on how to handle headers where the "content-type" is not "application/grpc" or similar. We should be safe and not reject such headers.

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.

One test (`CallerPollentsAreNotReferencedAfterCallbackIsRan`) was not waiting for a callback to be run before finishing when the EventEngine client is in use. With the iomgr implementation, `exec_ctx.Flush();` previously guaranteed that the callback would be executed before the test ended, but the EventEngine runs it in a separate thread, with the EventEngine shim providing its own isolated ExecCtx. This fix simply waits for the callback to be run before exiting, in the same way many other tests in this file wait on iomgr-based callback execution.

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.

`ProtoBitGen` provides a random number generator that returns values directly from fuzzer selected values, which allows us to test-into random selection algorithms deterministically.
Since the list of values provided by the fuzzer is limited, we need a fallback implementation. Previously we'd used something that was very correlated, and some of the distribution algorithms get into a very slow convergence mode when we do that (so we repeatedly return the same value for billions of iterations and cause timeouts in fuzzers).
Instead, when we run out of fuzzer supplied values, seed an mt19937 generator with the fuzzer selected values and use that from there on. Said generator will then produce values deterministically (for a given fuzzer input), but with a better distribution to allow convergence for fiddly algorithms.

A few improvements to the promise context system (more coming)
Allow subclassed contexts:
If we have multiple different kinds of a base context, allow `GetContext<Derived>()` to mean `down_cast<Derived*>(GetContext<Base>())` everywhere for brevity.
Allow custom context lookup:
For a base context type, allow customization of how that context is looked up.
These two together allow:
1. normalization of activity lookup and context lookup to the same syntax (so we can write `GetContext<Activity>()` everywhere now
2. Party & Activity to share a context, so that anywhere we need to do a party specific operation we can write `GetContext<Party>()->...` and safely know that it's the current activity *and* it's a party.

Only call constructors when absolutely necessary (empty trivially constructible types don't need construction!!)
Similarly for destructors, if the destructor is trivial it means C++ will do no work destructing it... let's not even do the virtual function call to get there.
(also fix a bug where we weren't calling this stuff anyway, and add a test that would have caught that)

A call execution environment for the V3 runtime.
The `CallFilters` class will ultimately be a (private) member of `CallSpine`, and the `StackBuilder` component will be used by a channel when all of the filters it needs are known to allow the call spine to start processing a call.
This is accompanied by a reasonably extensive test suite.
I expect to fine tune semantics, implementation, and tests over the coming weeks/months as we iterate to bring up the rest of the pieces.
