OvmfPkg: resolve PciSegmentLib
In the next patch we'll build "MdeModulePkg/Bus/Pci/PciHostBridgeDxe".
That driver depends on the PciSegmentLib class. Edk2 offers four
instances:
(1) MdePkg/Library/UefiPciSegmentLibPciRootBridgeIo/
Inappropriate here because it consumes
EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL, but
"MdeModulePkg/Bus/Pci/PciHostBridgeDxe" needs the library class for
producing that protocol.
(2) MdePkg/Library/PeiPciSegmentLibPciCfg2/
Restricted to PEIM, SEC, and PEI_CORE client modules.
(3) MdePkg/Library/DxePciSegmentLibEsal/
"uses ESAL services to perform PCI Configuration cycles"
(4) MdePkg/Library/BasePciSegmentLibPci/
A simple BASE library instance that sits on top of PciLib. This is our
choice. We can resolve PciSegmentLib to this instance for all module
types.
