UefiCpuPkg: Update SmmCpuFeatureLib pass XCODE5 tool chain

https://bugzilla.tianocore.org/show_bug.cgi?id=849

In V2, use "mov rax, strict qword 0" to replace the hard code db.

1. Use lea instruction to get the address instead of mov instruction.
2. Use the dummy address as jmp destination, and add the logic to fix up
the address to the absolute address at boot time.
