[MainUI] Semantics picker

[mherwege]

This PR changes the semantics picker to use a treeview.

This treeview is inherited from #3165 and enhanced (and this PR does include all changes from this previous PR as well). It therefore also introduces some enhancements in the semantic treeview maintenance.

The semantics treeview presents a searchable treeview of the semantic classes/properties, limited to what is relevant in the context. When used as a picker, radio buttons are used for picking. It has filter and expand capabilities, options to show the semantic name and synonyms and tooltips showing the semantic descriptions if available.

This PR can be review after #3165 (in which case I will rebase this one when done), or can be reviewed completely to cover both semantics maintenance and semantics picker. If this is the preference, I will rename this PR and close the previous one. @florian-h05 Please advise.
