KVM: VMX: Introduce test mode related to EPT violation VE
To support TDX, KVM is enhanced to operate with #VE. For TDX, KVM uses the
suppress #VE bit in EPT entries selectively, in order to be able to trap
non-present conditions. However, #VE isn't used for VMX and it's a bug
if it happens. To be defensive and test that VMX case isn't broken
introduce an option ept_violation_ve_test and when it's set, BUG the vm.
