Attachment: Bug 1939620 Part 1 - Skip test_accessiblecaret_cursor_mode.py on macOS debug due to frequent intermittent failures. r?#layout

The intermittent failures of these two tests happen on macosx1470-64.
Unfortunately, we cannot skip subtests on specific platforms. We still exercise
test_caret_not_jump_when_dragging_to_editable_content_boundary on input and
contenteditable elements, so I feel it is fine to skip them.

Attachment: Bug 1939620 Part 2 - Make test_drag_caret_from_front_to_end_across_columns more stable. r?#layout

This patch reverts the edit in Bug 1932800 - Fix caret baseline of empty inline
and text frames.

Additionally, convert <p> to <div> to remove the margin at the beginning of
the first column and the margin at the end of the second column. This ensures
that the first and second columns look the same.

In a contenteditable div, an image can be selected by dragging a cursor mode
AccessibleCaret across it. To avoid triggering AccessibleCaret's selection mode
during cursor mode dragging tests, we make the image non-selectable.
