OvmfPkg/BaseCachingPciExpressLib: Migrate BaseCachingPciExpressLib

Move BaseCachingPciExpressLib library from ArmVirtPkg to under OvmfPkg.
RISC-V Virt platform can leverage the same library to access PCI Express
registers through PCI Express base address set in PcdPciExpressBaseAddress
and cached in a global variable.
