Shorten more roles and states in braille #7188

Originally suggested in #214 (comment)

Ok this very old ticket describes a realy annoying problem with nvda's braille display output.

• in german nvda prints eg. (nicht verfübar) for not available. This output is important but should be replaced with some shorter text and it needs some tweak to be distinguished from the real text of the focuesed object.

Alternative str

1. Go to windows 10 settings > privacy
2. There are several toggle buttons here. On a braille display, "not pressed toggle button" is printed, wasting lots of space on a braille display
