tdf#148687 tdf#149173 tdf#149546 sw: fix crash with textboxes

Regression from 2110597ac730fa07dbbdd603fda82b182ed27c9e
"tdf#147485 sw: fix group shape crash using std::shared_ptr".

Details:

1) Using reference instead of copy assignment in SwTextBoxHelper.

2) Cleanup: Unused parts of SwTextBoxHelper were removed.

3) Fixing destruction of textboxes, in case when first the shape
is removed, with clearing all textboxes from the doc and the shape
before the pointer is released. All of this only have to be done if
the call is not coming from the swdoc dtor, unless there will be
double freeing.

4) Missing style conversion was fixed in writerfilter.

5) Don't import sections in textboxes, unless the hack of dummy
paragraph before tables in sections will be applied and the paragraph
with anchored objects inside will be removed with the objects;

6) ConvertTextRangeToTextFrame also fixed, so embed frames in
frames are imported from now. (Also textboxes in frames, this
can be useful when there is a floating table having group
textbox with nested complex content inside, or floating table
in floating table, etc...) Note: Follow up commit will enable
group textbox import in frames and tables.

7) Import of group textboxes with complex content in header/footer
was impossible, from now this is also supported both from DOCX and
ODT (test included).

8) Guard class for blocking unwanted recursive textbox sync
has been introduced, and maybe some speedup with group
textbox import has been achieved.

9) The anchor sync method got a new function which avoids
unnecessary sync when the anchor is the same.

10) Sync of As_char textboxes during layout calculation caused
crash so that has a workaround from now, for DOCX import anchor
change and Undo. That syncs starts before the layout calculation
so sync not needed later.

11) A memory leak was found in Undo, which has been fixed.

Note: layout test "testTdf147485Forcepoint" has to be limited
to Windows and Mac builds, because font substitution
causes crash on the Unix based systems.
