Norwegian Macbook Keyboard Tweaks (Ubuntu 24.04)

This patch modifies the Norwegian Macintosh keyboard layout on Ubuntu Linux to better match that of a modern Macbook's physical labels and expectations:

Replaces | (pipe) with ' (apostrophe) as the primary symbol for the key below esc
Promotes $ to Shift+4
Introduces € as AltGr+4
Demotes ¤ (currency) to Shift+AltGr+4 (since this is hardly used these days)
Swaps the order of the dead keys of the ´ (acute) and ` (grave) acents on the key to left of backspace ←
Enables access to higher level symbols by setting the right-most Alt ⌥ (Option) key as AltGr

Tested on Ubuntu 24.04 under GNOME Wayland on a "MacBookPro11,1" model from 2013, with a built in Norwegian keyboard.
