[WebGPU] Texture sample type is unnecessarily generated against auto-…

…generated layouts

Reviewed by Tadeu Zagallo.

The sample type of textures for auto-generated layouts is always a constant,
so it is not possible to validate them during bind group creation.

This was observed running the resource_init validation suite, which is currently
not running on EWS due to timeouts.
