SF: Physical Display ID duplication avoidance

Currently, there are no safeguards against duplicate display IDs when
creating displays of any kind (physical or virtual). In rare cases where
duplicates occur, they cause critical failures in display management.

This patch introduces avoidance logic and checks against display ID
duplicates in SurfaceFlinger around creation of physical displays.
