InputTracer: Separate the threading logic into a wrapper backend
InputTracer writes to the tracing backend interface. However, since
perfetto expects events to be written from a single thread, InputTracer
would write the events from a separate thread.
To simplify the logic inside InputTracer, remove the threading logic.
Instead, we introduce the ThreadingBackend class, which wraps around an
abitrary backend and forwards events to the inner backend from a new
thread.
Another benefit of this is that we no longer have to use the threaded
backend for tests, which makes the tracing part of InputDispatcher_test
deterministic.
