Don't do a style recalc when updating the composited layer of a plugin.

Don't do a style recalc when updating the composited layer of a plugin.

Since the renderer for the plugin always gets either a NormalLayer
or a ForcedLayer, it will have a RenderLayer whether it's composited
or not, so all we have to do is update it's self painting layer bit.

This is a followup to https://codereview.chromium.org/328553004.
