This PR is quite experimental! The goal is to see what is needed to support Limine with its native protocol and/or multiboot2.

Limine with its native protocol doesn't support VGA Text Mode but it places the kernel in higher half memory, which is interesting and something that the bootloader crate can't do with the 0.9 version.

Limine with the multiboot2 protocol does support VGA Text Mode, but doesn't enable long mode.
