UefiCpuPkg: Move StandardSignatureIsAuthenticAMD to BaseUefiCpuLib
Refactor StandardSignatureIsAuthenticAMD into BaseUefiCpuLib from
separate copies in BaseXApicLib, BaseXApicX2ApicLib, and MpInitLib.
This allows for future use of StandarSignatureIsAuthinticAMD without
creating more instances in other modules.
This function allows IA32/X64 code to determine if it is running on an
AMD brand processor.
UefiCpuLib is already included directly or indirectly in all modified
modules. Complete move is made in this change.
