We now can launch the kernel at 0xC0000000 (or 3 GiB mark) with paging enabled.
A lot of early main is currently not executed to keep debugging as simple as possible
during the initial testing of higher half kernel loading.
A lot of the implementation is straight from wiki.osdev.org/Higher_Half_x86_Bare_Bones. Thanks to all the folks
who keep that wiki updated, its really resourceful.
