MediaRecorder: add timecode validation to content_browsertests

Timecode was added recently (see bug) to the Spec and Chrome,
this CL adds some validation of the produced timecodes, which
boils down to they need to be monotonically increasing [1].

Bulk move
Blink>MediaStream>Recording ---> Blink>MediaRecording

owencm@chromium.org as PM for this.

Removing approval requested as that system is only for type=launch issues.

This change is minor enough that it doesn't need a Chrome launch review. It already has blink-dev@ LGTM so proceed.
