OvmfPkg: PciHostBridgeLib: set bus, IO and 32-bit MMIO windows in RootBus
The bus aperture is copied verbatim from InitRootBridge()
[OvmfPkg/PciHostBridgeDxe/PciHostBridge.c].
The IO and 32-bit MMIO apertures are matched to PlatformPei's settings.
PciHostBridgeLibDxe expects PciHostBridgeLib instances to advertize the
exact apertures.
