Wei Wang eeab491efd init: Support custom shutdown actions
We have been seeing panics and errors during shutdown sequence in
some vendor's platform, and it is required to disable error handling
during shutdown.

This CL separates the shutdown request to execute another "shutdown"
trigger at the beginning of shutdown stage. And vendor can use this
trigger to add custom commands needed for shutting down gracefully.

Bug: 38203024
Bug: 62084631
Test: device reboot/shutdown
