Revert "[shutdown] Shutdowm-shim becomes RebootWatcher"

This reverts commit 29d06623aa827e0db3a6c9e79441fe5dd02247b5.

Reason for revert: possible suspect for failures in go/bbid/8736427958045394561

Original change's description:
> [shutdown] Shutdowm-shim becomes RebootWatcher
>
> During high temperature shutdown which is initiated by power manager,
> shutdown-shim is not aware of the reboot and therefore would report
> incorrecct state. Driver manager will not terminate on time without
> the correct state.
>
> The change is a temporary solution to fix the reboot before a more
> complex solution.
