UefiCpuPkg/LocalApicLib: Rename GetProcessorLocation()

UefiCpuPkg/LocalApicLib: Rename GetProcessorLocation()

GetProcessorLocation() is too generic and will conflict with the API defined in
Galileo Board Software Package v1.0.0.

This update is just to rename GetProcessorLocation() to one specific name
GetProcessorLocationByApicId().
