[media] Replace MessageLoopProxy usage with ThreadTaskRunnerHandle

Replace MessageLoopProxy usage with ThreadTaskRunnerHandle in src/media.

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

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

Relanding https://codereview.chromium.org/1108773002/ CL as skyostil has added
task runners to more tests in CL https://codereview.chromium.org/1105373002/ .
So, i hope that intel mac release unittest break issue will resolve with it.

So, Could you please take a look.

Mostly the build break will not come with this CL now. If you have some
permissions to test for some mac bots test, could you please run for me.

Just in order to make sure, patch will not affect any Release bots.

I am not sure how to try that specific bot. You may just land it and then watch
the bot.
