libcamera: request: Add cookie to make request tracking easier
Applications often have to map requests queued to a camera to external resources. To make this easy, add a 64-bit integer cookie to the Request class that is set when the request is created and can be retrieved at any time, especially in the request completion handler. The cookie is completely transparent for libcamera and is never modified.
