spirv: Reuse helpers in vtn_handle_type()

Browse Source 
And change vtn_storage_class_to_mode() to accept NULL as
interface_type.  In this case, if we have a SpvStorageClassUniform, we
assume it is uses an ubo_addr_format, like the code being replaced by
the helper.

That assumption is a problem, but no different than the previous
code.
