Binbin Wu cd1ae7a89e hv: cat: isolate hypervisor from rtvm ...

Currently, the clos id of the cpu cores in vmx root mode is the same as non-root mode.
For RTVM, if hypervisor share the same clos id with non-root mode, the cacheline may
be polluted due to the hypervisor code execution when vmexit.

The patch adds hv_clos in vm_configurations.c
Hypervisor initializes clos setting according to hv_clos during physical cpu cores initialization.
For RTVM,  MSR auto load/store areas are used to switch different settings for VMX root/non-root
mode for RTVM.
