rhi: d3d: Fix up non-vsynced presentation
Doing Present(0, 0) is not necessarily sufficient to get rid of
blocking. It may very well start blocking after a few frames.
This does not apply to a non-flip-discard swapchain (when running
with QT_D3D_NO_FLIP=1), but for flip-discard we should also try using
DXGI_SWAP_CHAIN_FLAG_ALLOW_TEARING and DXGI_PRESENT_ALLOW_TEARING in
case a swap interval of 0 is wanted.
Pick-to: 6.3
Fixes: QTBUG-99949
