Fix types for `InputPatch` and `OutputPatch`

Fixes #34.

I'd declared these as if they were `InputPatch<T>`, but they are really `InputPatch<T,N>`.
This change fixes the declarations, and makes these types no longer inherit from the contrived `BuiltinGenericType`.
Instead they are more-or-less ordinary `DeclRefType`s using the same approach that `MatrixExpressionType` uses.
