UefiCpuPkg: Add SecCore module
Add SecCore module that uses the PlatformSecLib class for platform
specific actions. The SecCore module also uses a new PCD to
configure the size of the stack used in the SEC phase. If the
stack size PCD is set to 0, the stack is configured to use half
of the available temporary RAM.
