media: v4l2-ctrl: Add VP9 codec levels
Add menu control for VP9 codec levels. A total of 14 levels are defined for Profile 0 (8bit) and Profile 2 (10bit). Each level is a set of constrained bitstreams coded with targeted resolutions, frame rates, and bitrates. The definitions have been taken from webm project [1].
