[chrome/browser/chromeos/policy] Replace MessageLoopProxy usage with ThreadTaskRunnerHandle

Replace MessageLoopProxy usage with ThreadTaskRunnerHandle in chrome/browser module.

MessageLoopProxy is deprecated.
This basically does a search and replace of:

MessageLoopProxy::current() -> ThreadTaskRunnerHandle::Get().

MessageLoopProxy -> SingleThreadTaskRunner

Stopping commit.

AFAICT, you tried to "repair" the build breakage by just dropping the
cloud_external_data_manager_base.cc edits. The compiler error messages seem to
suggest that it's just missing the SingleThreadTaskRunner definition, so
including base/single_thread_task_runner.h should be the correct fix. Let me
know if I'm missing something.

Hi Mattias,
Yes, your review is absolutely correct :) I have updated the patch, PTAL

Thanks
