UefiCpuPkg: Add PlatformSecLib
Add PlatformSecLib class and PlatformSecLibNull instance
that is used by the SecCore. PlatformSecLibNull should
not be used in a platform build. Instead, it should be
used as a template for implementing a platform specific
instance of the PlatformSecLib library class.
(Sync patch r18635 from main trunk.)
