Laszlo Ersek 392a31467f OvmfPkg: introduce PciCapLib 
Add a library class, and a BASE lib instance, to work more easily with PCI
capabilities in PCI config space. Functions are provided to parse
capabilities lists, and to locate, describe, read and write capabilities.
PCI config space access is abstracted away.
