LibVideo/VP9: Replace (DCT|ADST)_(DCT_ADST) with struct TransformSet

Browse source 
Those previous constants were only set and used to select the first and
second transforms done by the Decoder class. By turning it into a
struct, we can make the code a bit more legible while keeping those
transform modes the same size as before or smaller.
