OvmfPkg: match PCI config access to machine type (if not USE_OLD_PCI_HOST)

If USE_OLD_PCI_HOST is FALSE, then we switch all executable module types
supported by DxePciLibI440FxQ35 to the following library instance stack:

  BasePciSegmentLibPci  [class: PciSegmentLib]
    DxePciLibI440FxQ35  [class: PciLib]
      BasePciCf8Lib     [class: PciCf8Lib]
      BasePciExpressLib [class: PciExpressLib]

Every module will select 0xCF8 vs. ECAM based on the OVMF platform type
(i440fx or Q35). Notably, MdeModulePkg/Bus/Pci/PciHostBridgeDxe is among
the affected drivers.

The BasePciExpressLib instance is where the PcdPciExpressBaseAddress PCD
fills its original role.
