MediaCaptureFromElement: add content_browsertests

This CL turns webrtc_canvas_capture_browsertest.cc
into webrtc_capture_from_element_browsertest.cc,
(note that they all come out of the same W3C spec).

It also adds a parameterized browser test
CaptureFromMediaElement that creates a MediaStream
out of a given media file played back in a
<video>/<audio> element. The test(s) pass when
there is a certain minimal amount of data
flowing.
