263: aarch64 improvements r=stlankes a=stlankes

Collections of patches to enable aarch64 support. This pull request is still  under development and doesn't support every feature of RustyHermit.
Co-authored-by: Stefan Lankes <slankes@eonerc.rwth-aachen.de>
Co-authored-by: Jonathan Schwender <schwenderjonathan@gmail.com>

Semihosting involves two machines: a target (the embedded device), and a host (such as a PC) that is connected to the target through a debug interface.

- rename files to separate architectures

- aarch64 does currently not support a network interface

This will help with testing (rusty-loader) since we currently
can't go very far in the kernel.
However if we reach this point, then that is already useful
for testing rusty-loader in CI.
This requires passing the `-semihosting` option to QEMU.
If this is not done or real hardware is used, a spinloop
will be entered.

- This currently relies on the fact that the bootloader only initialized 1 CPU (0)
- We enter boot_processor_main() and go up to the loop {}
- the loop {} prevents link time errors from stuff that is not working yet.
