Fix RichTextLabel table overlapping with next line
When calculating table height, RichTextLabel::_shape_line would increase the height when it reached the end of a complete row, or the final cell of the table. RichTextLabel::_resize_line would only increase the height at the end of a complete row, causing the height to ignore the final row if not all cells were populated. This would cause the final row to overlap with the following line in the RichTextLabel if it was the last visible line in the RichTextLabel, as _resize_line is called when updating scrolling properties. This change moves the common table size calculations to a separate function to reuse the code between _shape_line and _resize_line, keeping the final cell check that was used in _shape_line. Fixes #92603
