Reviewed by Carlos Garcia Campos.

With the Skia backend, we had an optimization to detect solid color
layers. The Skia code has been purged, but these bits remained. With
BlackBerry::Platform::Graphics::PlatformGraphicsContext, only the solid
color will be drawn anyway, so we don't need to detect such layers at
the WebCore level. Fixed by removing the setContentsToColor flavor of
LayerTiler::TextureJob.

BlackBerry::WebKit::WebOverlay still uses
TextureCacheCompositingThread::textureForColor() so that one can stay
for now.

This was dead code so no new tests.
