Add new onUidProcAdjChanged callback to be consumed by the camera
service.
The camera service needs to know when individual process oom adj scores
are changed in order to address bug #124224342. When two separate
processes are displayed in split screen and focus is switched between
them, both proc states will remain the same while their oom scores
change. This is a problem if both have access to the camera - we want
only one owner of the camera stream at any given time and for the app
in focus to be the one to own it.
This patch adds a new IUidObserver registration level for individual
process oom score changes. In addition a new callback has been added to
IUidObserver to track these changes.
