This patch adds validations to the multisampled color attachments and resolve targets. The resolve target must be a valid texture view, and it must follow the following validations: According to Vulkan SPEC: 1. If we set resolve target, the texture of the color attachment must be a multisampled texture, and the texture of the resolve target must be a non-multisampled texture. 2. The format of the resolve target must be the same as that of the color attachment. 3. The sample count of all the color attachments must be same. 4. The resolve target must have dawn::TextureUsage::OutputAttachment usage bit set when it was created. On D3D12: 1. ID3D12GraphicsCommandList::ResolveSubresource() method only allow resolving in a subresource of a texture, thus the level count and mipmap level count of the resolve target can only be 1. 2. ID3D12GraphicsCommandList::ResolveSubresource() method requires the dimension of the source and destination must match.
