lok: a11y: send list item prefix length to client
Implemented getListPrefixSize function which relies on
UNO_NAME_NUMBERING_LEVEL, UNO_NAME_NUMBERING character attributes.
The former provides the list item level, the latter is a boolean that
says if a prefix (bullet/number) is present or not for the list item.
It has been needed to modify
SwAccessibleParagraph::_getSupplementalAttributesImpl so that it
returns such properties for list item only and not for simple
paragraph too. In fact for a simple paragraph the default value for
the level property was returned which is 0 exactly the same value for
top list item.
