x86/platform: Move APIC ID validity check into platform APIC code
Move APIC ID validity check into platform APIC code, so it can be overridden when needed. For NumaChip systems, always trust MADT, as it's constructed with high APIC IDs. Behaviour verifies on standard x86 systems and on NumaChip systems with this, and compile-tested with allyesconfig.
