Draft: store 3 ShapeString parameters and remove font from prefs (#21054)

* Draft: store 3 ShapeString parameters and remove font from prefs

With this PR 3 ShapeString parameters are stored:
* ShapeStringFontFile: this replaces the old FontFile parameter.
* ShapeStringHeight
* ShapeStringText

The ShapeStringFontFile is just the last selected font file and not exposed in the Preferences editor.

Additionally:
* Changed the label of the text input box from "String" to "Text".
* Changed the label of the point reset button to sentence case.

* Remove faulty docstring
