Allow MediaStream constraints to specify higher than 30 FPS tab capture.

Allow MediaStream constraints to specify higher than 30 FPS tab capture.

This will allow true 720p/60fps tab/desktop capture, if configured
through the constraints (and the system hardware performance supports
it).  In addition, this will enable tab capture perf tests to run at
higher frame rates so that more-subtle regressions are caught.

A new hard upper-bound of 120 FPS is enforced with this change.

Sorry, my bad, I somehow missed that an additional approval was needed.

TBR'ing yzshen@, since there are no pepper changes other than the added arg to
the interface method defined in content/renderer/media.
