Tommi 9e46cf5cc5 Introduce a RunLoop class that supports the TaskQueue interface
on the current thread.

This simplifies writing async tests that use TaskQueue and doesn't
require spinning up a new thread for simple things. The implementation
is currently based on rtc::Thread, which could also be useful in
some circumstances while migrating code over to TQ.

Remove PressEnterToContinue from the test_common files since
it's very specific and only used from one file.
