REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1460
Add a new API ResetSystem to this ResetSystemLib instance.
It only adds the basic functions from ResetSystemRuntimeDxe.
Lacking of this interface may cause link error, if some drivers
use this new API and link to this library instance.
Make the ResetPlatformSpecific's parameters same with the
interface in Edk2 repo.
Notes:
This library API only provide a basic function of reset. If
the consumers want full functions, they should use the instance
in the MdeModulePkg and make sure the depex driver is dispatched.
