libcamera: Switch to FrameBuffer interface
Switch to the FrameBuffer interface where all buffers are treated as external buffers and are allocated outside the camera. Applications allocating buffers using libcamera are switched to use the FrameBufferAllocator helper. Follow-up changes to this one will finalize the transition to the new FrameBuffer interface by removing code that is left unused after this change.
