In V2, use mov rax, strict qword 0 to replace the hard code db.
Use the dummy address as jmp destination, and add the logic to fix up
the address to the absolute address at boot time.

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.
3. On MpFuncs.nasm, use ExchangeInfo to record InitializeFloatingPointUnits.
This way is same to MpInitLib.
