Shuo A Liu 112f02851c hv: Disable XSAVE-managed CET state of guest VM 
To hide CET feature from guest VM completely, the MSR IA32_MSR_XSS also
need to be intercepted because it comprises CET_U and CET_S feature bits
of xsave/xstors operations. Mask these two bits in IA32_MSR_XSS writing.

With IA32_MSR_XSS interception, member 'xss' of 'struct ext_context' can
be removed because it is duplicated with the MSR store array
'vcpu->arch.guest_msrs[]'.
