Fix DX11 shared textures

Right now creating a texture from a native texture with D3D11_RESOURCE_MISC_SHARED_NTHANDLE  will fail unless it is also D3D11_RESOURCE_MISC_SHARED_KEYEDMUTEX. This combination is recomended but not mandatory acording to the specification: https://learn.microsoft.com/en-us/windows/win32/api/d3d11/ne-d3d11-d3d11_resource_misc_flag
