[PATCH v2 1/2] OvmfPkg/BaseCachingPciExpressLib: Migrate BaseCachingPciExpressLib

["Abner Chang" <abner.chang@hpe.com>]

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.
