Move RenderObject::isTransparentOrFullyClippedRespectingParentFrames() to RenderLayer
https://bugs.webkit.org/show_bug.cgi?id=195300

Reviewed by Simon Fraser.

Source/WebCore:

Move isTransparentOrFullyClippedRespectingParentFrames() from RenderObject to RenderLayer, since this function
asks questions about RenderLayers rather than their renderers. No change in behavior.

* rendering/RenderLayer.cpp:
(WebCore::enclosingFrameRenderLayer):
(WebCore::parentLayerCrossFrame):

Some static helpers currently in RenderObject that walk up the layer hierarchy through subframes are redundant
with static helpers in RenderLayer. Now that isTransparentOrFullyClippedRespectingParentFrames exists in
RenderLayer, simply use this existing helper instead and split logic to grab the enclosing layer around the
owner element of a frame into a separate helper.

* rendering/RenderLayer.h:
* rendering/RenderObject.cpp:
(WebCore::enclosingFrameRenderLayer): Deleted.
(WebCore::parentLayerCrossingFrameBoundaries): Deleted.
(WebCore::RenderObject::isTransparentOrFullyClippedRespectingParentFrames const): Deleted.

Moved from RenderObject.

* rendering/RenderObject.h:

Source/WebKit:

Refactor some logic to use isTransparentOrFullyClippedRespectingParentFrames on RenderLayer rather than
RenderObject; introduce a helper method to ask whether the enclosing layer of a renderer is transparent or
clipped.
