tdf#128611 sw: improve rotated text layout in table cells

The problem was that in case a table with 1 row and 2 cells has rotated
text in the A1 cell, then the row height is 0, so we aggressively try to
break up the text into multiple lines. Then the A2 cell adds more
content, so the row height is increased, but the A1 cell is not
re-layouted to make use of the increased amount of vertical space.

A similar (but working) situation is vertical alignment of cell content,
there adding more content to A2 re-formats A1.

Fix the problem in a similar way: track if a text frame contains at
least one rotated portion, and throw away the portions of the text frame
at the end of SwCellFrame::Format(), after vertical alignment is
handled.
