Source/WebKit:

* PlatformEfl.cmake: Removed ewk_view_tiled related files.

Source/WebKit/efl:

We didn't use ewk_view_tiled very long time while we focused webkit2/efl.
There are many bugs and we don't have plan to fix them.
Instead, We will use WebCore's TiledBackingStore and it looks more stable.
