Add ASL support for preloads

Introduces a new asl-file tag in framework-sysconfig.xml with a package
and path attribute to configure asl file path for preloaded apps. On
first boot or OTA, SystemConfig will read and store the path on
PackageSetting which will become the source of truth for the file path.
