This implements a simple bootloader that is capable of loading ELF64 kernel images. It does this by using QEMU/GRUB to load the kernel image from disk and pass it to our bootloader as a Multiboot module. The bootloader then parses the ELF image and sets it up appropriately. The kernel's entry point is a C++ function with architecture-native code. Co-authored-by: Liav A <liavalb@gmail.com>
