Introduce a flag for feature policy optimized image policy violation

When an image element violates some optimized image policy, it should be
rendered with inverted color.

This CL introduced a flag to indicate if an image should be rendered
with inverted color.

In addition, this CL added code to invert the color when the flag is on.

Update optimized image policy logic to invert color from style to paint

When violating optimized image policies, images should be rendered with
inverted color. This CL
https://chromium-review.googlesource.com/c/chromium/src/+/1030758
added the inverting code in style.
This CL moves the inverting code into paint instead.

Tests will be added as image policies are implemented. But this has
been manually verified to work.
