Sync rhi backingstore d3d12 behavior with Quick

Browse Source 
When adding the D3D12 code path in widgets it seems it was ignored that
the retry-with-WARP logic was present both for D3D11 and 12 in Qt Quick.

For consistency, the same logic must be used. Right now widgets only has
the retry logic for D3D11.

Pick-to: 6.6
