[idd] capture: split software and hardware frame processors

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.
