powerpc/64s/exception: Move all interrupt handlers to new style code gen macros

Aside from label names and BUG line numbers, the generated code change
is an additional HMI KVM handler added for the "late" KVM handler,
because early and late HMI generation is achieved by defining two
different interrupt types.

* 0x300 - Data Storage Interrupt (DSI)

* DAWR matches also fault here, as do RC updates, and minor misc errors e.g.,
* copy/paste, AMO, certain invalid CI accesses, etc.
*
* This interrupt is delivered to the guest (HV bit unchanged).

* entry was insufficient. RPT goes straight to full page fault.
