Present SGX related MSRs to guest if SGX is supported.
- MSR_IA32_SGXLEPUBKEYHASH0 ~ MSR_IA32_SGXLEPUBKEYHASH3:
SGX Launch Control is not supported, so these MSRs are read only.
- MSR_IA32_SGX_SVN_STATUS:
read only
- MSR_IA32_FEATURE_CONTROL:
If SGX is support in VM, opt-in SGX in this MSR.
- MSR_SGXOWNEREPOCH0 ~ MSR_SGXOWNEREPOCH1:
The two MSRs' scope is package level, not allow guest to change them.
Still leave them in unsupported_msrs array.
