[google_maps_flutter_web] Ability to animate camera with duration #159265
Description
Use case
User should be able to configure camera update duration on Web platform.
Camera animation duration is supported currently only on Android and iOS platforms.
Related to #39810
Proposal
Maps Javascript API does not support setting animation duration for camera controls by default.
Maps Javascript API -documentation has example how to implement custom animation duration with Tween.js library.

Similar behaviour could be gained using TickerProvider and stepping camera position between start (current) and end (target) position.
