UefiCpuPkg/LocalApic.h: Remove duplicated/conflicted definitions
#define MSR_IA32_APIC_BASE_ADDRESS is duplicated with #define MSR_IA32_APIC_BASE
defined in UefiCpuPkg/Include/Register/ArchitecturalMsr.h, so we could remove it
and update the modules to use MSR_IA32_APIC_BASE from ArchitecturalMsr.h.
Structure MSR_IA32_APIC_BASE conflicts with #define MSR_IA32_APIC_BASE defined
in UefiCpuPkg/Include/Register/ArchitecturalMsr.h, so we could remove it and
update the modules to use structure MSR_IA32_APIC_BASE_REGISTER from
ArchitecturalMsr.h.
v5:
1. Update SourceLevelDebugPkg to use APIC Base MSR from ArchitecturalMsr.h.
