MacDue f7bf14605c LibWeb: Remove PaintBorders recording painter command
`Painting::paint_all_borders()` only uses `.draw_line()` for simple
borders and `.fill_path()` for more complex cases. These are both
already supported by the `RecordingPainter` so removing this command
simplifies the painting API.

Two test changes:

css-background-clip-text: Borders are now drawn via the AA painter
(which makes them closer to how they appear in other browsers).

corner-clip-inside-scrollable: Borders removed (does not change test)
due to imperceptible sub-pixel changes.
