wgpu dx12 requests to Texture that if its usage has STORAGE_BINDING, D3D12 resource needs to have D3D12_RESOURCE_FLAG_ALLOW_UNORDERED_ACCESS. The equivalent of D3D12_RESOURCE_FLAG_ALLOW_UNORDERED_ACCESS in D3D11 is D3D11_BIND_UNORDERED_ACCESS. Therefore, D3D11 textures in ExternalTextureD3D11 also require D3D11_BIND_UNORDERED_ACCESS if STORAGE_BINDING is used. Differential Revision: https://phabricator.services.mozilla.com/D192976
