libcamera: framebuffer: Add Fence to FrameBuffer
Add to the FrameBuffer::Private class a unique pointer to a Fence. The Fence will be used to signal the availability of the Framebuffer for incoming data transfer. The Fence will be associated to a FrameBuffer at Request::addBuffer() time, and if correctly signalled, reset by the core at Request queue time. If a FrameBuffer completes with errors, due to a Fence wait failure, the Fence will still be owned by the FrameBuffer and it is application responsibility to correctly reset it before reusing the buffer.
