This fixes a very strange TSAN flake seen in an internal test (b/268292646), which seems to have been introduced in grpc/grpc#32326. I've included an example of the TSAN failure below, for future reference. I don't fully understand what is causing this failure. It looks like the async callback from a previous picker update caused the pick to be re-queued but then got stuck draining queued callbacks in its `ExecCtx` instance, while the async callback from the next picker update had already failed the call. But the part I don't understand is why the call combiner cancellation callback wound up scheduled on the `ExecCtx` instance from the first thread -- that seems likely to be caused by either the `WorkSerializer` or maybe `ExecCtx` work-stealing, but the exact details are likely to be hard to nail down. Switching from `EventEngine::Run()` back to `ExecCtx::Run()` seems to fix the flake, so that's what I'm doing in this PR. I find this work-around deeply dissatisfying, especially since I do not fully understand the root cause of the problem. However, given that we are working toward eliminating the `FilterBasedLoadBalancedCall` code entirely as part of the promise conversion, this problem is probably not worth further investigation. ```

third_party/grpc/src/core/ext/filters/client_channel/client_channel.cc:2780:5 in grpc_core::ClientChannel::FilterBasedLoadBalancedCall::~FilterBasedLoadBalancedCall() ```

Long story here: CallbackAlternativeCQ operates a thread pool which processes a completion queue and then directly invokes the completion function in the same thread. This thread pool is initialized on first Ref() and unallocated on last Unref(). When running an in-process synchronous server (as we do for tests, using this https://github.com/google/tensorstore/blob/master/tensorstore/internal/grpc/grpc_mock.h), called by an async() interface caller, if the async() callback happens to drop the last reference to the grpc Channel, then the channel shutdown will attempt to run in one of the the CallbackAlternativeCQ threads. This will cause a deadlock/race condition, as `CallbackAlternativeCQ` is not designed to shutdown itself. When this deadlock happens, `pthread_join(pthread_id_)` will return `EDEADLK` and the thread will keep running. However `EDEADLK` is silently ignored by Join() so `CallbackAlternativeCQ::Unref` will continue to delete the underlying grpc_completion_queue, leading to a `SIGSEGV` later in the process. https://github.com/grpc/grpc/blob/97ba9871324cb68b93f22fd1860934392cd476ee/src/cpp/common/completion_queue_cc.cc#L115 This adds an assert that pthread_join succeeded, which is useful as it avoids a later SIGSEBV. Alternatively, the thread implementation could gpr_log the errorcode before asserting.
