  [GTK] Use DMABuf and WebKit IPC for rendering instead of wpe/x11
https://bugs.webkit.org/show_bug.cgi?id=252988

Reviewed by Žan Doberšek.

Instead of the wpe rendered, which uses a nested wayland compositor, and
x11, which uses a redirected xcomposite window, we can make the web
process render always into a pbuffer using mesa surfaceless platform and
export the rendered texture using DMAbuf to be consumed by the UI
process. This way the rendering is independent from the platform
(wayland/x11), and in the UI process we just import the DMABuf into a
texture that we pass to GTK for rendering into the web view widget. If
under X11 GTK uses GLX instead of EGL we manually import the DMABuf
using libgbm to create a cairo surface that we can pass to GTK without
using GL.
