spirv: Add block decorations with a transform

Browse Source 
Any struct which is used as the store type of a buffer variable needs
to have a block decoration. If that struct is nested inside an array
or another struct, we wrap it inside another struct first.

This removes the SPIR-V backend's reliance on the [[block]] attribute,
which will soon be deprecated and removed.
