Test of VMCS processor-based controls

This test checks that a nested VM-entry fails if reserved bits in the
primary processor-based VM-execution controls are not set properly
(according to either the IA32_VMX_PROCBASED_CTLS MSR or the
IA32_VMX_TRUE_PROCBASED_CTLS MSR, as appropriate). It also checks that
a nested VM-entry fails if the "activate secondary controls"
VM-execution control is set and a reserved bit is set in the secondary
processor-based VM-execution controls (according to the
IA32_VMX_PROCBASED_CTLS2 MSR).
