meson: Revamp qt5qml plugin and example build code
Stricter and simpler. For example, now we properly error out when gstreamer-gl-1.0 was not found when the qt5 plugin is enabled or when a C++ compiler is not enabled. Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/merge_requests/587>
