Running this test, which sets each sample of a 4 count multisample texture to a different color and then uses textureLoad(multisampledTexture, vec2u(0), sample_index) to read each of the samples to a storage buffer in Chrome on Linux AMD OpenGL gets different results than the other APIs

normal results

sample_index: 0  value: 1,0,0,0  si: 0
sample_index: 1  value: 0,1,0,0  si: 1
sample_index: 2  value: 0,0,1,0  si: 2
sample_index: 3  value: 0,0,0,1  si: 3

GL results

sample_index: 0  value: 1,0,0,0  si: 0
sample_index: 1  value: 0,0,0,1  si: 3
sample_index: 2  value: 0,0,1,0  si: 2
sample_index: 3  value: 0,1,0,0  si: 1

I ran into this issue writing the textureLoad WGSL tests

We think maybe swizzling the index in textureLoad on the GL backend is enough to fix this? If not, another solution is to disallow textureLoad on texture_multisample_2d<???> textures in compat. other ideas?
