The goal was to fix shader,validation,decl,var:binding_collisions:*, but in order
to pass that test this validation needs to during during shader creation time, while
we current run it at pipeline creation time. However, moving the validation requires
a significantly larger change, which will happen later, but this seemed like a
worthwhile validation to have in the meantime.
