Bug 1562847 - Disable double buffering with compositor when device reset happens r=nical,bas

Browse Source 
When double buffering is enable with compositor, DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL is used without DirectComposition. There are some devices that swap chain with DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL does not work well. In this case, device reset happens very often. To avoid the situation, the double buffering needs to be disabled when device reset happens.
