Feature: add multiprocessing support like limine

No description provided.

aparently you can start other cpus pretty easily in limine:
#[used]
#[unsafe(link_section = ".requests")]
pub static MP_REQUEST: MpRequest = MpRequest::new().with_flags(RequestFlags::X2APIC);

let mp_response = MP_REQUEST.get_response().unwrap();
for cpu in mp_response.cpus() {
cpu.goto_address.write(entry_point_from_limine_mp);
}
