70c314ce5 [google_maps_flutter_web] Fix getScreenCoordinate, zIndex of Circles (flutter/plugins#4298) (#89895)

* Updated with proper docs

* Add the casting

Fuchsia is deprecating amber_ctl and replacing it with pkgctl.
This change removes the FuchsiaAmberCtl class and replaces it
with the FuchsiaPkgctl class and updates the usages appropriately.
