Overlay manifest setting by package manager 

Using overlay manager to get package name of overlay apk.
And parse it's resources to get config value directly.

Register PRE_BOOT_COMPLETED to set up the value.

Bug: 134558563
Test: Preload RRO with "is_launcher_enabled:false", flash all device,
      boot to verify if DocumentsUI launcher icon hidden.
Test: Preload RRO with "is_launcher_enabled:false", factory reset,
      and verify if DocumentsUI launcher icon hidden.
