Move cadence-aware hardware capture and immediate software capture behind a common frame processor interface. Keep shared damage tracking and frame-buffer ownership in the base processor, and move stateless format, resource, and rectangle helpers into CFrameProcessorUtil. Decouple frame-buffer resources from CSwapChainProcessor by passing the device dependencies they use directly.
