[GTK] [CMake] Fix the video and audio build
https://bugs.webkit.org/show_bug.cgi?id=126464

Reviewed by Philippe Normand.

.:

* Source/cmake/OptionsGTK.cmake: GStreamer files look for USE(GSTREAMER) and USE(WEBAUDIO_GSTREAMER),
so define those when appropriate. Web audio is one by default in autotools, so turn it on for cmake
as well.

Source/WebCore:

* PlatformGTK.cmake: Complete the audio and video source lists.

Tools:

* GtkLauncher/CMakeLists.txt: Add GStreamer includes and libraries, since GtkLauncher uses it.
