  [Coordinated Graphics][GraphicsLayerTextureMapper] Crash with an animation of 
drop-shadow and currentColor
https://bugs.webkit.org/show_bug.cgi?id=297499

Reviewed by Miguel Gomez.

After <https://commits.webkit.org/293027@main> added a new filter type
DropShadowWithStyleColor to support the drop-shadow filter with
currentColor, a crash happened in
TextureMapperLayer::paintSelfAndChildrenWithIntermediateSurface if a
content has an animation of the filter.

GraphicsLayerCA doesn't accept animaitons of any drop-shadow filter.
Do the same thing for GraphicsLayerCoordinated and
GraphicsLayerTextureMapper too.
