[GTK] Remove support to enable/disable experimental features

https://bugs.webkit.org/show_bug.cgi?id=167586

Reviewed by Michael Catanzaro.

As requested in bug #167578 we should remove the support to enable/disable
experimental features in WebKitGTK+.
One reason is that CSS Grid Layout is going to be enabled by default now,
so we don't need it to be in this file.
Another is that this support needs to be rewritten to use
the enumerable experimental features API.

* PlatformGTK.cmake:
* UIProcess/API/gtk/WebKitSettings.cpp:
(webKitSettingsConstructed):
* UIProcess/gtk/ExperimentalFeatures.cpp: Removed.
* UIProcess/gtk/ExperimentalFeatures.h: Removed.
