OvmfPkg: Call CcProbe in SecMain.c instead of TsIsEnabled
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3902
TdIsEnabled() uses the CPUID instruction. At this point, exception
handling is not established and a CPUID instruction will generate
a #VC and cause the booting guest to crash.
CcProbe() checks Ovmf work area to return the guest type. So call
of CcProbe() instead of TdIsEnabled() to fix the above issue.
