libcamera: request: Add Request::Private::prepare()
Add a prepare() function to the Private Request representation. The prepare() function is used by the PipelineHandler class to prepare a Request to be queued to the hardware. The current implementation of prepare() handles the fences associated with the Framebuffers part of a Request. The function starts an event notifier for each of those and emits the Request::prepared signal when all fences have been signalled or an optional timeout has expired. The optional timeout allows to interrupt blocked waits and notify the Request as failed so that it can be cancelled.
