Issue #3294269: Fixes of Drupal 8 compatibility issues after adding non-existent service "file_url_generator",
simply moving the needed @file_url_generator service methods in the inner @geofield_map.marker_icon service,
with @todo notes to refactor all this in favour of only Drupal core 9 & 10.

fix of 'Issue #3293108: Argument 1 passed to Drupal\geofield_map\Services\MarkerIconService::getIconFileManagedElement() must be of the type int, null given'

Drupal.org doc update for new 8.x-2.80 release: extends Geofield Map Views capability to render data features from more Geofield-s sources.

Refinement of Automatic HTML5 Geolocation: The initial automatic set of the Geofield value to the user location will work only for the first Widget Geofield Map (also in case of multivalue field),
because to complex to resolve in case of multi Geofields in te same Entity.
(Issue #3280092: Automatic HTML5 Geolocation possible?)

Implement the Weight feature property in the Geofield Map Formatter and View style, to implemnet Map Feature z-index Ordering.

MarkerIconService coding standards fixes.
