VideoBackends: Use VideoCommon shader generators for efb2tex copies.

Browse Source 
This will generate one shader per copy format. For now, it is the same
shader with the colmat hard coded. So it should already improve the GPU
performance a bit, but a rewrite of the shader generator is suggested.

Half of the patch is done by linkmauve1:
VideoCommon: Reorganise the shader writes.
