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.
