Introduce TestBrowserThreadBundle::RunUntilIdle()

I'm tired of having to call a static method deep into content/test just
to RunUntilIdle. This brings TestBrowserThreadBundle to feature parity
with ScopedTaskEnvironment in this space which makes sense as the two
are interchangeable.

This also comes closer to robliao's goal of getting rid of
TaskScheduler::FlushForTesting() (used by
content::RunAllTasksUntilIdle()).

And lastly, it makes cleanups in  crbug.com/823797  less ugly as some
of them will need to go from using a ScopedTaskEnvironment to a
TestBrowserThreadBundle and reverting them back to static global flush
is ugly.

Deprecate content's test_utils.h APIs for task running in favor of modern task running APIs.

And introduce TestBrowserThreadBundle::RunIOThreadUntilIdle() to replace the only method
that didn't have an immediate replacement.

[Documentation] RunAllTasksUntilIdle() is still useful in browser tests.

Deprecating was a bit too strong as this is still useful in few
browser tests (which don't have TestBrowserThreadBundle since it's a
unit test construct).
