KVM: arm64: Move vcpu PC/Exception flags to the input flag set
The PC update flags (which also deal with exception injection)
is one of the most complicated use of the flag we have. Make it
more fool prof by:
- moving it over to the new accessors and assign it to the
input flag set
- turn the combination of generic ELx flags with another flag
indicating the target EL itself into an explicit set of
flags for each EL and vector combination
- add a new accessor to pend the exception
This is otherwise a pretty straightformward conversion.
