Functions: Add materialize methods for generic mutable virtual array

Similar to how `GVArray_For_VArray` implements `materialize_impl` to
forward the work to its non-generic virtual array, we can do the same
thing for the mutable version, `GVMutableArray_For_VMutableArray`.

This commit should have no visible changes, since as far as I can tell
the only user of this class does not implement special materialize
methods anyway.
