Change the GDT push logic
...
Instead of looking for a zero field, we now keep track of the next free index in a separate field. This avoids the bug that the high u64 of a pushed TSS descriptor is treated as empty.

Test the handler_with_error_code macro in a different way
...
We now take stack_frame as a immutable reference and we shouldn't write to a &. So the old test example (page faults as breakpoints) becomes even more hacky. Instead, we're now deliberately entering an endless page fault loop to check our iretq logic.
