direct3d11: only send the HDR metadata when they change 

Newer Windows issue this warning if we send metadata with each picture:

DXGI WARNING: IDXGISwapChain4::SetHDRMetaData: Redundant invocation on unchanged
metadata could result in presentation performance inefficiency. [ MISCELLANEOUS WARNING #295: ]

Similar code as done in 269540817f for VLC 4.0.
