Don't check for package changes in AOSP mode

Summary:
PS1: start Home button longpress support

Enable Home Longpress Action

Properly handle GlowRing when LP state changes. Also added
AOSP Mode compliance for removed package checking. No need
to check when AOSP mode is enabled.

Test Plan: test and merge, but it's solid
