tdf#118370 Draw: add option to consolidate multiple textObjs

This gives the user a tool to consolidate multiple textboxes
into a single textbox. First the user selects a group of
textframes, and then runs the consolidate text function.
This will REPLACE the marked textframes with a single textbox
combining all of the text. The function inspects the text
fragments to see if they end in sentence-ending punctuation.
If not, then the next textbox's content is appended to it
instead of starting a new pargraph. It is the user's responsibility
to afterwards fix up paragraphing, and set paragraph properties.

The rational for this patch is to simplify making major text
changes on PDFs imported into Draw, since each paragraph is
currently broken into tiny character-property textbox fragments.
Copy/paste from the PDF itself doesn't keep character attributes,
so it is hard for a user to re-create the text.

This is related to tdf#32249, but as a comment says, a better
solution would be to write an entire text-focused PDF import,
rather than just pick up the pieces. And I agree, but considering
this simple patch took me a couple of weeks of frustration,
I'm obviously not the person to do that. And since the bug
has been open for 9 years, likely no one else will either.
Thus, this pick-up-the-pieces tool to help the end user.

This initial patch works only with textFrames, but can
easily be adjusted to consolidate other HasText() SdrObjects.
However, that tended to produce unexpected results, so everything
other than OBJ_TEXT is explicitly excluded.
(Thus general shapes with text, callouts, text-along-path etc
are ignored.)
