shader: More efficient state-based shader input fetching

Browse Source 
Previously every input was fetched as a matrix.  Now, every input is fetched as a vector, with matrices taking up multiple vectors.  This saves a lot of copying and a lot of space in the cache.

Furthermore, integer state-based inputs can be defined (for future use)

Naming still needs to be revised, since it's called the "mat part cache" etc.
