Remove MessageLoop::current()->RunUntilIdle() in media.

Remove MessageLoop::current()->RunUntilIdle() in media.

This CL replaces MessageLoop::current()->RunUntilIdle() with
RunLoop().RunUntilIdle() in media.

In files where this replacement is made, it adds this include:
  #include "base/run_loop.h"
And removes this include if it is no longer required:
  #include "base/message_loop/message_loop.h"

Why?
- The fact that there's a MessageLoop on the thread is an
  unnecessary implementation detail. When browser threads
  are migrated to base/task_scheduler, tasks will no longer
  have access to a MessageLoop but they will be able to use
  RunLoop.
- MessageLoop::RunUntilIdle() is deprecated.

Steps to generate this patch:
1. Run message_loop_cleanup_3.py (see code on the bug).
2. Run tools/sort-headers.py on modified files.
3. Run git cl format.
