The LocalApicLib does not provide a function to manage the state of the
Local APIC SoftwareEnable bit in the Spurious Vector register. There
are cases where this bit needs to be managed without side effects to.
other Local APIC registers. One use case is in the DebugAgent in the
SourceLevelDebugPkg.

Use Family from CPUID 01 to detect support for the Local APIC Base Address MSR (MSR_IA32_APIC_BASE_ADDRESS).
If this MSR is not supported, then use Local APIC Base Address from the PCD PcdCpuLocalApicBaseAddress.

2. Save/restore CPU Interrupt state around sending IPI. It could avoid sending IPI be interrupted by CPU interrupt handler.
3. Add note for SetApicMode() API that must not be called from an interrupt handler or SMI handler.
