Add show/hide descriptions from configuration page to all forms

D.o procid experiment

This issue would be a good case study to evaluate procid #2154143: Evaluating Procid, a tool to help the drupal community improve the consensus building process for d.o issues →
You do not have to use procid to work on this issue, but if you want to, your feedback would be very helpful.

------
The ability to hide descriptive text allows the user to reduce cognitive load and increase efficiency.
A cleaner, less cluttered UI is easier to visually parse and navigate and the descriptive text is only helpful when the user needs it.
Categorized as a usability bug because the heavy cognitive load of excessive descriptive text throughout Drupal significantly impacts users.
