reset: detect highest severity guest dynamically

Browse Source 
For guest reset, if the highest severity guest reset will reset
system. There is vm flag to call out the highest severity guest
in specific scenario which is a static guest severity assignment.

There is case that the static highest severity guest is shutdown
and the highest severity guest should be transfer to other guest.
For example, in ISD scenario, if RTVM (static highest severity
guest) is shutdown, SOS should be highest severity guest instead.

The is_highest_severity_vm() is updated to detect highest severity
guest dynamically. And promote the highest severity guest reset
to system reset.

Also remove the GUEST_FLAG_HIGHEST_SEVERITY definition.
