[d3d11] Always export correct shared handle type from ::GetSharedHandle and ::CreateSharedHandle

Browse Source 
Before we just assumed that the calls here would match the corresponding flag value (D3D11_RESOURCE_MISC_SHARED -> ::GetSharedHandle, D3D11_RESOURCE_MISC_SHARED_NTHANDLE -> ::CreateSharedHandle), but it turns out that its possible to set both flags and use both methods.  Now we always tell Vulkan to export a KMT handle if D3D11_RESOURCE_MISC_SHARED is present, and use openKmtHandle to get an NT handle when needed.
