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
