MdeModulePkg: Update PciEnumeratorSupport to ignore OptionRom if needed
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429
Function of UpdatePciInfo() in PciEnumeratorSupport.c is used to update
the bar information for those incompatible PCI device. It is the right
place to check if the OptionRom need to be ignored.
According to "Table 20. ACPI 2.0 & 3.0 QWORD Address Space Descriptor
Usage" in PI Spec 1.7, Type-specific flags can be set to 0 when Address
Translation Offset == 6 to skip device option ROM (do not probe option
rom BAR).
