The VMTRACE feature is depends on Platform/Arch HW and code support and now
can be used only on x86 HVM with Intel VT-x (INTEL_VMX) enabled.
This makes VMTRACE support optional by introducing HVM Kconfig option:
- CONFIG_VMTRACE to enable/disable the feature.

Tamas - any chance of an ack here?
Grygorii - chasing missing acks is generally the submitter's responsibility.
