spirv: Allow block-decorated struct types for constants

Whenever a struct type is decorated Block or BufferBlock we turn that
into a GLSL_TYPE_INTERFACE.  Since these decorations can end up random
places, we should allow them for constants.

Closes: #3252
Fixes: 9d0ae777dd6 "spirv: Use interface type for block and buffer..."
