Improve <input type=color alpha> performance on macOS
https://bugs.webkit.org/show_bug.cgi?id=286803
rdar://143955048
Reviewed by Aditya Keerthi.
Using data: URLs here resulted in annoying flickering when moving the
alpha slider quickly.
Using SVG directly in the shadow tree ran into
https://bugs.webkit.org/show_bug.cgi?id=287472 so therefore we use a
div element with a polygon clip-path. This results in additional render
layers, but websites will likely not have a lot of these controls so
that seems okay.
