* feat(camera_feedback): gate CAMERA_IMAGE_CAPTURED by param
Some cameras implementing the MAVLink Camera Protocol (e.g. reached via
TRIG_INTERFACE=MAVLink) report CAMERA_IMAGE_CAPTURED themselves. The
autopilot's camera_feedback also emitted this message, so the ground
station saw duplicate capture messages for every shot.
Add a bool 'report' field to the camera_capture message, set from the new
CAM_CAP_REPORT parameter, and gate the CAMERA_IMAGE_CAPTURED stream on it.
When reporting is disabled the capture is still published and logged for
geotagging; only the MAVLink message to the ground station is suppressed.
CAM_CAP_REPORT applies live (no reboot); it only gates a MAVLink message,
unlike CAM_CAP_FBACK which reconfigures the capture pin.
