kvm-unit-tests: VMX: Add test cases for instruction interception

Add test cases for instruction interception, including four types:
1. Primary Processor-Based VM-Execution Controls (HLT/INVLPG/MWAIT/
RDPMC/RDTSC/MONITOR/PAUSE)
2. Secondary Processor-Based VM-Execution Controls (WBINVD)
3. No control flag, always trap (CPUID/INVD)
4. Instructions always pass
