LibVideo/VP9: Move persistent context storage to a different header

Browse source 
Moving these to another header allows Parser.h to include less context
structs/classes that were previously in Context.h.

This change will also allow consolidating some common calculations into
Context.h, since we won't be polluting the VP9 namespace as much. There
are quite a few duplicate calculations for block size, transform size,
number of horizontal and vertical sub-blocks per block, all of which
could be moved to Context.h to allow for code deduplication and more
semantic code where those calculations are needed.
