  [Skia] Implement support for shadows that ignore transforms
https://bugs.webkit.org/show_bug.cgi?id=270175

Reviewed by Carlos Garcia Campos and Nikolas Zimmermann.

When creating the drop shadow filter, if state.shadowsIgnoreTransforms()
is true, render the drop shadow with trasformed coordinates and blur
radius, by adjusting them against the CTM inverse.

This is enough to make various canvas tests happy. Some of them are still
failing with off-by-one colors, and it's not clear why.
