Hide UDFPS background on transition Home => AOD
There are two transitions that end up on AoD:
1. Lock screen => AoD
2. Home => AoD
We need to track these two transitions separately.
* When the device transitions from LS => AoD, the icon
has a circle background protection and shows and full
(not dashed) icon.
* When the device transitions from Home => AoD, the icon
can immediately start appearing at its AoD location,
showing the AoD-dashed UDFPS icon, without any bg protection.
