mesa: Add a new function for getting the nonconst sampler array index
If the array index is not a constant expression, the existing support
will assume a zero offset (giving us the sampler index of the base of
the array).
For dynamically uniform indexing of sampler arrays, we need both that
and the indexing expression.
