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.

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.

`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.

Using `AF_UNSPEC` for both IPv4 and IPv6 queries does not work in all cases. Specifically, for `localhost:<>`, c-ares only returns the IPv6 record i.e. `::1`.

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.

Eventually for call-v3 we're going to want to have registration of filters generate the appropriate glue into the channel runtime to execute a call.
Begin that process now and gradually by introducing the new syntax and allowing a piecemeal migration to it - by the time we're done converting filters to the v3 APIs we'll also have the registration piece done.

We encountered an api_fuzzer test case that adds a huge number of addresses that all immediately fail to connect, but it set max_backoff to 0, so there was a giant busy loop where pick_first was constantly trying to connect to subchannels with no delay. The FuzzingEventEngine was getting stuck in a tick loop, always accumulating more tasks that needed to be executed immediately, so it could never make forward progress on the test case.
This PR fixes the problem by adding a fixed 1us delay if the task's delay is 0 and the test case has not provided any more fixed delays.
(Unfortunately, I cannot include the test case that triggered the problem in this PR, because it winds up exceeding the RBE stdout limit.)
Fixes b/310664846.
