Input: atkbd - correctly map F13 - F24

Currently only F23 is correctly mapped for PS/2 keyboards.

According to this table:

- F24 and Zenkaku/Hankaku share the same scancode, but since in real world
Zenkaku/Hankaku keys seem to just use the tilde scancode, this patch binds the
scancode to F24. Note that on userspace side the KEY_ZENKAKUHANKAKU keycode is
currently not bound in xkeyboard-config, so it is (mostly*) unused anyway.

* Qt on Wayland and therefore KDE on Wayland can see the keypress anyway for
some reason and it is actually used in a touchpad toggle shortcut, but this is
currently being fixed in both KDE and xkeyboard-config to make this less weird,
so it could directly be fixed to correctly handle the F24 keypress instead.

- The scancodes for F13-F22 are currently unmapped so there will probably be no
harm in mapping them. This would also fix the issue that some of these keys
can't be mapped as the target from userspace using the `setkeycodes` command.
