OvmfPkg/IncompatiblePciDeviceSupportDxe: Ignore OptionRom in Td guest
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429
Host VMM may inject OptionRom which is untrusted in Td guest. So PCI
OptionRom needs to be ignored if it is Td guest. According to
"Table 20. ACPI 2.0 & 3.0 QWORD Address Space Descriptor Usage"
PI spec 1.7, type-specific flags can be set to 0 when Address
Translation Offset == 6 to skip device option ROM.
