Add validations on the format of a resolve target

Browse Source 
This patch adds the validations on the format of a resolve target
according to the latest updates in WebGPU SPEC. WebGPU SPEC only
supports the below texture formats being used as the resolve target
of a render pass encoder:
- R8Unorm
- RG8Unorm
- RGBA8Unorm
- RGBA8UnormSrgb
- BGRA8Unorm
- BGRA8UnormSrgb
- R16Float
- RG16Float
- RGBA16Float
- RGB10A2Unorm
