LibGfx: Stop storing SkYUVAPixmaps in YUVData

Browse Source 
Storing these was pointless, since they're only used briefly to provide
the info needed to upload the buffers to the GPU.

For BT.2020 coefficients, we can just say that the bit depth is 16 bits
since we're always bit replicating to that for Skia's shaders.
