ArmPkg/ArmCpuLib: Replaced complex functions ArmCpuSynchronizeWait & ArmCpuSynchronizeSignal by sev & wfe
Previsouly the synchronization of MpCore was using the SGI (Software
Generated Interrupt) to synchronize MpCore during the early boot.
This commit replaced this mechanism by the more appropriate SEV/WFE
instructions (Send/Wait Event instructions).
That also eases the port to a new cpu/platform.
