Add pixel output for VideoCaptureStream usage in RenderProcessHostTest

These tests currently pass by luck as they are missing EnablePixelOutput() call
that is necessary to get proper pixel values out of <video>, that is necessary
for detecting events.

This CL adds a test class instance to setup these tests properly.
