libcamera: pipeline_handler: Prepare Request
Before queueing a request to the device, any synchronization fence from the Request framebuffers has to be waited on. Connect the Request::Private::prepared signal to the function that queues requests to the hardware and call Request::Private::prepare(). When the waiting request queue is inspected, verify if it has completed its preparation phase and queue it to the device.
