LibGfx+LibMedia: Send video frames to Skia as subsampled YUV

Browse Source 
This saves us from having our own color conversion code, which was
taking up a fair amount of time in VideoDataProvider. With this change,
we should be able to play high resolution videos without interruptions
on machines where the CPU can keep up with decoding.

In order to make this change, ImmutableBitmap is now able to be
constructed with YUV data instead of an RBG bitmap. It holds onto a
YUVData instance that stores the buffers of image data, since Skia
itself doesn't take ownership of them.

In order to support greater than 8 bits of color depth, we normalize
the 10- or 12-bit color values into a 16-bit range.
