Geofield mapbox gl

This will add a new field formatter as map in a geofield field, using the mapbox services.

The module https://www.drupal.org/project/mapbox_gl is mandatory.
After enabled you can choose the formatter of a geofield as a "mapbox gl" , in manage display of any
entity that has a geofield field.

To make it work you have to obtain an api key from mapbox. And then choose the representation
of the point:

- Marker: https://docs.mapbox.com/mapbox-gl-js/example/marker-from-geocode/
- Circle: https://docs.mapbox.com/mapbox-gl-js/example/multiple-geometries/
- Icon: https://docs.mapbox.com/mapbox-gl-js/example/geojson-markers/
- Custom image: https://docs.mapbox.com/mapbox-gl-js/example/add-image/
- Custom Image from other field in the same entity, with the choosen image view
mode.

All comes with tooltip with the choosen view mode of the same entity.
(https://docs.mapbox.com/mapbox-gl-js/example/popup-on-click/)

If any error of recursive str_replace happens, make it sure that an apropiate view mode for
the entity is not using the geofield_mapbox_gl formatter.
