[webkit-gtk] Enable UI_SIDE_COMPOSITING for WebKit2 GTK

[Gwang-Yoon Hwang]

Hello, WebKit-Gtk.

I'm planning to work on UI_SIDE_COMPOSITING support in WebKit2 GTK port.
 https://bugs.webkit.org/show_bug.cgi?id=92368

The main reasons of this work listed below.
1.  We are facing on the problem "Xlib: unexpected async reply" on specific
embedded system. Because WebProcess and UIProcess have "thread unsafe Xlib
connection" at the same time, we need to maintain single Xlib connection.

2. To maintain single Xlib connection on WebKit2 Gtk, we can reuse
UI_SIDE_COMPOSITING feature that already implemented in WebKit2 QT port.

3. We can optimize UI_SIDE_COMPOSITING together with other ports (QT, EFL)

3. In the embedded system, it is important to reduce workload of the main
thread/process. :)

Thanks.
