x86/apic: Use u32 for APIC IDs in global data
APIC IDs are used with random data types u16, u32, int, unsigned int,
unsigned long.
Make it all consistently use u32 because that reflects the hardware
register width and fixup the most obvious usage sites of that.
The APIC callbacks will be addressed separately.
