rhi: d3d11: Rework swapchain effect handling
Use FLIP_DISCARD swapchains only on Win10, stick
with DISCARD otherwise. This may fix the swapchain
creation problems on Windows 7.
Add a QT_D3D_NO_FLIP env.var. to make it possible to
disable using FLIP_DISCARD even on Win10. This is there
for troubleshooting purposes.
Finally, fix the backbuffer handling. What we originally
ported from the D3D12 backend of Qt Quick is not quite how
DXGI used to work with D3D11 and earlier. GetBuffer() can
only be used to query index 0, and that's the backbuffer,
the rest is managed internally. Follow this model.
As an added bonus, disable Alt+Enter.
