lineage-sdk: Import power menu related classes

Different parts of the system need to check if advanced reboot is enabled,
so just move the method here and include it in said different parts.

The global actions constants also used to live in the frameworks, but as
they include our own additions and are also accessible by LineageParts,
place them here from now on.
