tdf#60382 sw offapi: add change tracking of table/row deletion

This is a minimal extension of the text range based change
tracking to record and apply table row and table deletions
with full Undo/Redo support.

Add property IsNotTracked to com::sun::star::text::TextTableRow.

During recording of track changes, deletion of table rows wasn't
recorded: the rows removed completely with their text content.
Now the deletion deletes the cell content with change tracking,
setting also IsNotTracked property of table rows to FALSE. If
all tracked deletions were accepted in a row, and the result is
an empty row, the row will be removed, if its IsNotTracked
property is FALSE.

Note: Deletion of empty lines isn't recorded (they are simply
deleted). Hiding deleted rows hasn't been supported yet in
the Hide Changes mode.

OpenDocument supports only track changes of text ranges, but
not changes of the table structure, e.g. deletion of table
rows. For the native export it needs to extend ODF, and
depending on this future extension, can be based also on
SwExtraRedlineTable (which lacks of recording and Undo/Redo,
but supports OOXML round-trip of tracked table changes).

"Add support for 'Table Row Redlines' in SW core" and its
follow-up commits.
