Log Message:
-----------
PlaceholderRenderingContext is not consistent wrt isGPUBased() accessor
https://bugs.webkit.org/show_bug.cgi?id=275053
rdar://129160039
Reviewed by Antti Koivisto.
CanvasRenderingContext::isGPUBased() was used for two
conflicting purposes:
1. Downcasting to GPUBasedCanvasRenderingContext
2. Forcing RenderLayerBacking creation for canvas RenderLayers.
1. is a bit dangerous, as PlaceholderRenderingContext is-not-a
GPUBasedCanvasRenderingContext.
Forcing RenderLayerBacking / RenderLayer creation also used
CanvasRenderingContext::isAccelerated().
Rename CanvasRenderingContext::isAccelerated() to
CanvasRenderingContext::delegatesDisplay(). The property means
that the context is able to directly replace the GraphicsLayer contents.
