MdePkg/IndustryStandard/Pci23: add vendor-specific capability header

Browse Source 
Revision 2.2 of the PCI Spec defines Capability IDs 0 through 6,
inclusive, in Appendix H. It reserves IDs 7 through 255.

Revision 2.3 of the PCI Spec adds Capability IDs 7 through 0xC, inclusive,
in Appendix H. Capability ID 9 stands for "Vendor Specific".

Add the EFI_PCI_CAPABILITY_ID_VENDOR macro and the
EFI_PCI_CAPABILITY_VENDOR_HDR structure type to MdePkg/IndustryStandard,
in order to describe this capability header.
