glTF exporter: add an export identifier

Can be useful in case of other addons that call glTF exporter by code, and using some Extension.
To avoid having an impact on regular glTF exporter, dev can now call the glTF exporter with 'gltf_exporter_id',
and using it in export_settings to check if we are coming from an addon or, if empty, from a regular export
