libcamera: pipeline: raspberrypi: DmaHeaps: Use UniqueFD for a file descriptor

Manages a file descriptor owned by DmaHeaps for a dma handle by UniqueFD. Furthermore, DmaHeaps::alloc() creates a new file descriptor and the returned file descriptor is owned by a caller. This also clarifies it by changing the returned value to UniqueFD.
