val: interface struct with builtins must be Block (#4665)
For a shader input/output interface variable of structure type:
If the structure has BuiltIn members, then the structure type
must be Block decorated.

Otherwise, the variable, or the struct members must have locations,
but nothing can have both a location be a BuiltIn.

Implements validation needed to reject the example in
