Allowlist for exempting packages from being marked as stopped by default
An allowlist for packages that should not be scanned in a "stopped" state.
Bug: 249514169
Test: Manual. Added a system package in the allowlist, performed factory
reset and checked the stopped state of the same package after 1st boot.

+This XML defines an allowlist for packages that should not be scanned in a "stopped" state.
+When this feature is turned on (indicated by the config config_stopSystemPackagesByDefault in
+core/res/res/values/config.xml) packages on the system partition that are encountered by
+the PackageManagerService for the first time are scanned in the "stopped" state. This allowlist
+is also considered while creating new users on the device. Stopped state is not set during
+subsequent reboots.
+
+Example usage
+ 1. <initial-package-state package="com.example.app" stopped="false"/>
+ Indicates that a system package - com.example.app's initial stopped state should not be set
+ by the Package Manager. By default, system apps are marked as stopped.
+ 2. <initial-package-state package="com.example.app" stopped="true"/>
+ Indicates that a system package - com.example.app's initial state should be set by the
+ Package Manager to "stopped=true". It will have the same effect on the
+ package's stopped state even if this package was not included in the allow list.
+ 3. <initial-package-state package="com.example.app"/>
+ Invalid usage.
