Zide Chen b627c2c979 hv: switch IA32_TSC_AUX between host/guest through VM Controls ...

Currently guest IA32_TSC_AUX MSR is loaded manually right before VM
entry, and saved right after VM exit.

This patch enables VM-Entry Control and VM-Exit Control to switch
MSR IA32_TSC_AUX between host and guest automatically. This helps to
keep vcpu_thread() function and struct acrn_vcpu cleaner.

Also it removes the dead code of intercepting IA32_TSC_AUX.
