libcamera: ipu3: Implement memory handling
Implement buffer allocation and release in IPU3 pipeline handlers. As the pipeline handler currently supports a single stream, provide two internal buffer pools for 'viewfinder' and 'stat' video devices, and export the 'output' video device buffers to the stream's pool. This works around the fact that the ImgU requires buffers to be queued on all its outputs, even when they are not in use. Share buffers between the CIO2 output and the ImgU input video devices, as the output of the former should immediately be provided to the latter for further processing.
