UefiCpuPkg:Remove code to wakeup AP and relocate ap

After the code to load mtrr setting, set register table,
handle APIC setting and Interrupt after INIT-SIPI-SIPI
is moved, the InitializeCpuProcedure() only contains
following code logic:
1.Bsp runs ExecuteFirstSmiInit().
2.Bsp transfers AP to safe hlt-loop

During S3 boot, since APs will be relocated to new safe
buffer by the callback of gEdkiiEndOfS3ResumeGuid in
PeiMpLib, Bsp doesn't need to transfer AP to safe hlt-loop
any more. SmmRestoreCpu() in CpuS3 only needs to runs the
ExecuteFirstSmiInit() on BSP. So remove code to wakeup
AP by INIT-SIPI-SIPI and remove code to relocate ap to
safe hlt-loop.
