Remove non Coordinated Graphics code path from cmake build system after r142169

After http://trac.webkit.org/changeset/142169, Coordinated Graphics, Tiled Backing Store, Graphics Surface, ...  are mandatory for EFL WK2, so we can remove these guards from cmake files too.

USE(TILED_BACKING_STORE) is still being used in source code. So, I'm not sure whether we can remove this here.

We need to mention what you do this file.

I'll add descriptions to the modified files, thanks for pointing it out.

If we leave it in the code, the build will fail in case of minimal build. None of the other ports use it, so it's safe to remove it.

If so, you can just change isEfl() with 0. Are you sure whether other ports never enable it again ?

Let's see all options one by one:
- default => isEfl() : It means it is enabled on EFL by default, but 
  --minimal option would disable this mandatory feature. It isn't good.
- default => 0 : It means it would be disabled always on EFL - on minimal
  and on normal build too. It isn't good.
- Deleting it from FeatureList.pm would cause problem if we would like
  to make TILED_BACKING_STORE optional. But it isn't optional at all.
  It is mandatory on EFL and not used / not work on other ports.

Hi,
If I am right, TILED_BACKING_STORE can't be an optional nowadays because it's meaningless without Coordinated Graphics.
And if other port want to use it, it can be used like other port specific features, WTF_USE_SOUP and WTF_USE_CROSS_PLATFORM_CONTEXT_MENUS.

So, removing it from FeatureList.pm is fine to me.

FYI,
If other port want to use TILED_BACKING_STORE, there are only two options.
(1) use Coordinated Graphics.
(2) implement missing parts such as TiledBackingStoreBackend, implementation class of Tile and painting path for the pure TiledBackingStore.

I roughly listed missing parts about option (2), but it's to use TiledBackingStore on the WebKit1.
If someone want to use it on the WebKit2, it require much more modules.

With your patch, it looks not required anymore.

> Source/cmake/OptionsEfl.cmake:216
> +set(USE_GRAPHICS_SURFACE 1)

It's already not required.

Ossy, I see. I wondered whether other ports will use it future. However, it looks GTK port won't use it. Looks good if you fix Ryuan's comments as well.

I don't think that this bug touches mac related code so this is surely false warning.
