6977fc05d9 VMX: adjust RFLAGS saved into guest state on VMEXIT according to VMX documentation: 
For APIC-access VM exits and for VM exits caused by:
- EPT violations
- EPT misconfigurations
- page-modification log-full events or
- SPP-related events
the value saved depends on whether the VM exit occurred during delivery of an event through the IDT ...

also handle RFlags saved if VMEXIT was caused directly by an event that would normally be delivered through the IDT

should fix #215

0eab037907 dynamically allocate VMCB_CACHE only if SVM is actually enabled by CPU model 
also reduces include dependency on svm.h

89d992b5b8 fixed (#214) wrong MSR name typo in MSR error message 
in real mode exceptions should not push error code to stack so the same should be for VMEXIT due to HW exception from unrestricted real mode guest (fixes #211)

1bf18b8aae ! CPUID: Added TigerLake CPU definition (features CET and CLWB support) 
- CPU code refactor, remove uses of bx_bool datatype and use C++ classic bool instead.
  This enable better compiler optimizations and reduce binary size

f90e5f4f44 Add initial implementation of the CET (Control Flow Enforcement Technology) emulation according to SDM071 
Only missing items (to be added soon):
  - Supervisor Shadow Stack EPT Control is not implemented yet
  - SMM placing for SSP
Currently have to be added manually to some CPUID model, for example to ICL-U
To enable configure with --enable-cet
