Combine whitelisting of system apps and permission changes on upgrade
- Load all data needed for both operations in parallel
- Avoid re-loading of already loaded data
- de-dup whitelistings between the two methods
Performance of RuntimePermissionsUpgradeController.onUpgradeLocked on
first boot with this change on cuddlefish-userdebug:
~ 200ms loading data
~ 20ms processing data
~ 90ms applying whitelisting state
~ 0 granting permissions (does not happen for new users, only on upgrade)
Test: Measured performance. Checked that permissions were whitelisted
