Using the GstContext mechanism, it is possible to find if the pipeline shares a GstGLContext, even if we are not to negotiating GLTextureUpload meta. This is interesting because we could negotiate system memory caps feature, but enable DMABuf if the GstGLContext is EGL with some extensions. https://bugzilla.gnome.org/show_bug.cgi?id=766206
