rhi: d3d11: Rework timestamp query logic

Browse Source 
For offscreen frames this is a significant improvement since
now we will have timings available after endOffscreenFrame()
returns, meaning the behavior matches the Vulkan, D3D12,
and Metal backends in this regard.

It also enables getting timings in frames that have
QRhi::finish() or QRhiCommandBuffer::begin/endExternal()
calls.
