libcamera: allocator: Add FrameBufferAllocator to help applications allocate buffers
The FrameBuffer interface is based on the idea that all buffers are allocated externally to libcamera and are only used by it. This is meant to create a simpler API centered around usage of buffers, regardless of where they come from. Linux however lacks a centralized allocator at the moment, and not all users of libcamera are expected to use another device that could provide suitable buffers for the camera. This patch thus adds a helper class to allocate buffers internally in libcamera, in a way that matches the needs of the FrameBuffer-based API.
