UefiCpuPkg/MpInitLib: add struct MP_HAND_OFF_CONFIG

Browse Source 
Move the WaitLoopExecutionMode and StartupSignalValue fields to a
separate HOB with the new struct.

WaitLoopExecutionMode and StartupSignalValue are independent of
processor index ranges; they are global to MpInitLib (i.e., the entire
system). Therefore they shouldn't be repeated in every MpHandOff GUID
HOB.
