This patch does not impact functionality. It aims to clarify the
synchronization flow between the BSP and APs to enhance code
readability and understanding:
Steps #6 and #11 are the basic synchronization requirements for all
cases.
Steps #1 is additional requirements if the MmCpuSyncModeTradition
mode is selected.
Steps #1, #2, #3, #4, #5, #7, #8, #9, and #10 are additional
requirements if the system needs to configure the MTRR.
Steps #9 and #10 are additional requirements if the system needs to
support the mSmmDebugAgentSupport.
