UefiCpuPkg/MpInitLib: Add ApWakeupFunction() executed by assembly code

Browse Source 
ApWakeupFunction() is the first C function executed from AP reset vector. When
APs waken up at the first time, it will sync BSP's MTRR setting and load
microcode on APs and collect APs' BIST information.

When AP tasked finished, it will place APs it one loop specified by ApLoopMode.

v5:
  1. Rename ApCFunction to ApWakeupFunction to meet naming convention.
