Andrew Cooper 68d757df8d x86/pv: Options to disable and/or compile out 32bit PV support ...

This is the start of some performance and security-hardening improvements,
based on the fact that 32bit PV guests are few and far between these days.

Ring1 is full of architectural corner cases, such as counting as supervisor
from a paging point of view.  This accounts for a substantial performance hit
on processors from the last 8 years (adjusting SMEP/SMAP on every privilege
transition), and the gap is only going to get bigger with new hardware
features.
