[edk2-devel] [Patch V2 1/3] UefiCpuPkg/MpInitLib:Repeat WakeUpAp of loading microcode,Syncing MTRR.

["Yuanhao Xie" <yuanhao.xie@intel.com>]

This patch replicates the WakeUpAp operation, encompassing both
microcode loading and MTRR synchronization, regardless of whether
MpHandOff is NULL.

The purpose of this patch is to enhance the review process.
The separation in this patch is aimed at facilitating a more
straightforward review, with the ultimate goal of eliminating the
microcode loading functionality for the second time Mp initialization.
