wpe: Rewrite wpesrc as a glbasesrc subclass
And since it no longer allocates memories itself, this fixes issues with fakevideosink. A lot of code previously copied from gltestsrc is no longer needed thanks to the glbasesrc super-class. Fixes https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/1046
