tdf#115523 sw_redlinenum: show correct, also original numbering

in Show Changes mode, according to the name "Show Changes" and
according to the interoperability requirements.

Instead of the fake numbering which counted the deleted list items
in Show Changes mode, e.g.:

"3. This was the third originally, but now it's the second list item."

now show the correct number followed by the original number within braces:

"2.[3.] This was the third originally, but now it's the second list item."

Note: the tabulators after the longer numbering are replaced with spaces
to avoid messy indentation in Show Changes mode.

New enum values for the alternative lists:

SwListRedlineType::SHOW     - the original (fake) numbering in Show Changes mode
SwListRedlineType::HIDDEN   - the original numbering of Hide Changes mode, and
new numbering in Show Changes mode
SwListRedlineType::ORIGTEXT - the new numbering of Show Changes mode to show
the original numbering of the deleted or inserted list items

Follow-up to commit c180c9447256588fe5e7991e06642883574760ae
"sw_redlinehide_3: add second SwNodeNum to SwTextNode".
