Added CameraStereoZedOC (Zed Open Capture driver).

* Added CameraStereoZedOC (Zed Open Capture driver). Calibration: added stereo baseline option, show warning if fx is very different after stereo calibration.

* Fixed build without Zed Open Capture. Fixed "any" prefix added to all tools when WITH_ZEDOC=ON. UI: fixed Zed Open Capture action not disabled when not built with it.
