bgra8unorm storage textures without bgra8unorm-storage, should generate WGSL error? #4711
Description
if you have
@group(0) @binding(0) var tex: texture_storage_2d<bgra8unorm, read>;
But you have not requested the 'bgra8unorm-storage' feature, you don't get WGSL error at shader module creation time.
This seems inconsistent with the idea that in compat you do WGSL error for these (#4568):
@group(0) @binding(0) var tex: texture_storage_2d<rg32float, read>;
@group(0) @binding(1) var tex: texture_storage_2d<rg32sint, read>;
@group(0) @binding(2) var tex: texture_storage_2d<rg32uint, read>;
