Power profiles daemon support
don't show profile options if
- power-profiles-daemon is accessible
- GNOME Shell >= 41 (it will then be in the main status menu)
if GNOME Shell < 41 don't even try to check for power-profiles-daemon and directly use asusctl
This is also the first step to just use it as a GFX switcher.
A lot of code can be removed later when the power profiles daemon support is the default one and when asusctl does not support the profiles anymore.
