Emilio Cobos Álvarez 015a3aeb12 Bug 1757827 - Improve win11 overlay scrollbars. r=saschanaz,cmartin
Tweaks are:

 * Round the scrollbar track (when visible, which is almost never).
 * Make the scrollbar thinner.
 * Move the thumb closer to the edge.

All these changes match closer the Windows 11 style, and there are no changes
for other existing styles.
