i386/cpu: Make the Intel PT LIP feature configurable
The current implementation will disable the guest Intel PT feature
if the Intel PT LIP feature is supported on the host, but the LIP
feature is comming soon(e.g. SnowRidge and later).
This patch will make the guest LIP feature configurable and Intel
PT feature can be enabled in guest when the guest LIP status same
with the host.
