Fix UnobservedTaskException from SemaphoreSlim.WaitAsync (#60890)

* Fix UnobservedTaskException from SemaphoreSlim.WaitAsync

If a SemaphoreSlim.WaitAsync times out, it correctly returns false, but it also results in TaskScheduler.UnobservedTaskException being raised unexpectedly, due to internal use of a faulted task whose exception isn't observed.  This fixes that by marking any such exceptions as having been observed.

* Fix wasm build
