Disallow specialization constants in certain contexts

The initialization of a specialization constant must not use other
specialization constants.

Arrays sized by a specialization constant inside structures are broken
by design because member offsets in SPIR-V are required to be literals.
Changing the size through specialization would at best leave empty space
in the struct and at worst overlap other members.
