Jiawei Shao ab1a2b7407 Add validation on format when creating a multisampled texture
This patch adds the validation on the texture format when we create
a texture with sample count > 1 according to the latest updates in
WebGPU SPEC.

Below formats can't be used to create a multisampled texture:
- R32Uint, R32Sint, RG32Uint, RG32Sint, RG32Float, RGBA32Uint,
  RGBA32Uint, RGBA32Sint, RGBA32Float
- All compressed formats
- RGB9E5UFloat
