sw lok, .uno:SetDocumentProperties: expose value of custom document properties

LOK API clients currently have no knowledge about document properties.

Clients like Zotero that want to store custom properties on documents
need a way to read and write such properties. This commit focuses on the
reading side.

Add a getter for .uno:SetDocumentProperties that allows filtering for a
certain prefix, this way the returned value can contain only the
relevant information.

Rework doc_getCommandValues() and SwXTextDocument::getCommandValues() a
bit, so adding new getters require less duplication.
