[iOS] Create GLIC Promo Infra Part 2

This CL:
- Registers GLICPromoDisplayHandler in
registerStandardPromoDisplayHandlerPromos
- Implements a basic scene agent to pipe promo manager infra
- Starts scene agent behind kPageActionMenu flag in scene controller

This CL was meant to have incomplete code in order to make the CL size
smaller.
