BC-7520 - a11y messages

[hoeppner-dataport]

Short Description

Implement some logic to ensure that aria-live messages, that are send in polite mode, do not interrupt the user, while typing some text into a text-element.

The problem occurs because the CK5-Editor is not recognized as an input field by the browser and by that the user interactions in it are not handled the same way as if he/she would type in a normal textfield.
The solution that was implemented:

1. switches the notifier into a queueing mode that collects all messages that are generated
2. considers every key being pressed in the CK5-Editor as an interaction that should delay the notifications
3. switches back to write mode after 1500ms have passed without the user pressing any key in the CK5-Editor
4. writes all messages when being in write-mode
