libpayload/arch/x86: Add support for initializing the APIC
This is just the bare minimum required to initialize the APIC. I only support xAPIC and chose not to support x2APIC. We can add that functionality later when it's required. I also made the exception dispatcher call apic_eoi so that the callbacks won't forget to call it. BUG=b:109749762 TEST=Booted grunt and verified that depthcharge continued to function and that linux booted correctly. Also verified GDB still works.
