Summary [GTK] Use DMABuf and WebKit IPC for rendering instead of wpe/x11

Instead of the wpe rendered, which uses a nested wayland compositor, and x11, which uses a redirected xcomposito 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), 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 any of the required extensions is not available we can fallback to current platform dependent approach.
