This reverts commit 6330260f7d.

Reason for revert: Need by this CL which was also reverted:
https://dawn-review.googlesource.com/c/tint/+/55402

Original change's description:
> Validate that in/out storage classes are not used
>
> Use a DisableValidationDecoration to allow these storage classes only
> for variables generated by the SPIR-V sanitizer.
>
> Fix or delete all of the tests that were wrongly using these storage
> classes.
>
> Bug: tint:697
