This is a reland of 878c8c7d

Reason for reland: media_blink_unittests should no longer be flaky after
updating the condition in UpdateBackgroundVideoOptimzationState(). The
flakiness derived from CancelableOnceCallback/Closure::IsCancelled()
returning true after the callback is run.

Original change's description:
> Finish base::Bind -> Once/Repeating migration for media/blink and /cdm
>
> Use of base::Bind, ::Callback, etc. is deprecated in favor of the more
> explicit Once/Repeating versions. Despite being marked as fixed, a few
> directories have some remaining uses that were missed in the conversion.
> This cl fixes those stragglers in the media/blink and media/cdm
> directories. The presubmit is also enabled for these directories to
> avoid any future regressions.
