Add all of the functionality to allow the kernel to boot itself.
...
This is a trimmed down version of Syncboot integrated into the kernel.
The plan is, eventually, to allow the kernel to be booted by Syncboot, but that'll take a lot of research into QEMU.
This was just quicker to do.
This isn't tested, as I still need to figure out how to compile the EFI entry point separately.
They can be linked together, however. That's why the kernel is designed around a PE32+ format.

It's interrupt time, baby.
...
This should bring the kernel to a working state.
Don't forget that the interrupts.c file absolutely must be compiled with -mgeneral-regs-only.
All the other files absolutely must be compiled with -mavx2.
