qdutils: Add display config to qdutils

This API is meant for system level users that need to get/set
various display attributes that are normally not available via
the regular Android framework channels.
Initially the APIs exposed are to check HDMI status, get display
attributes and set HSIC data.
Only physically connected displays are supported for now.
