[Backport] Security bug 378725734 (1/2)

Cherry-pick of patch originally reviewed on
https://dawn-review.googlesource.com/c/dawn/+/215936:
Validate layout constraints for all address spaces

The WGSL spec has a non-normative note that the layout constraints
should be validated for all non-host-shareable address spaces, using
the same constraints as for storage.

See linked bug for details of why this is important.
