refactor: remove dead GStreamer bambusrc plugin and its build dep
gstbambusrc was the GStreamer source element for the old wxMediaCtrl2 Wayland player, its only consumer (deleted in the previous commit). The new FFmpeg player handles bambu:/// URIs through the Bambu C API instead. Drop the plugin and the gstreamer-1.0 / gstreamer-base-1.0 REQUIRED pkg-config dependencies that existed solely for it.
