media: Add VideoFrameLayout class.

As current VideoFrame cannot represent real buffer layout, I
propose to add a new class, VideoFrameLayout, to store size
of physical buffers codec needs as well as format and
coded_size of a frame. Also, it stores stride (bytesperline)
per buffer to calculate each color plane's size.

BUG=b:110815424
TEST=pass media_unittests --gtest_filter=VideoFrameLayout.*
