TD Compliance test not aligned with SDM and TDX module spec #341

Hi

Here is the snippet of test log running from TD guest.

CR4_SET_X86_CR4_PCE skipped is expected, as TD has perfmon enabled MSR_IA32_PRED_CMD is a Write Only MSR from SDM, why perform Read operation, expecting no exception. Same with IA32_X2APIC stuff, no write allowed from SDM. Could you please update test pattern per SDM? thanks

Thanks Fan's input. I'd like to update the tests. BTW, could you please provide the public TDX spec you're using. There're too many versions.
