Add per-viewport AOV selection (stageView.py GetRendererAovs port)

Browse Source 
Exposes the render delegate's available AOVs in the gear popup under a new
"AOV" sub-menu. Selecting an AOV calls SetRendererAov on the engine and
persists the choice per-viewport in viewport_settings.ini. Switching the
render delegate resets the AOV to "color", matching stageView.py's
_handleRendererChanged. Menu is greyed-out when the delegate reports no AOVs.
