Code Review

This pull request adds support for CameraUpdate.newLatLngBoundsWithEdgeInsets across the Android, iOS, and Web implementations of the google_maps_flutter plugin. The changes include updating the platform interface, implementing the new camera update type in the platform-specific code, and adding relevant tests. A critical issue was identified in the Objective-C conversion logic where the isKindOfClass: check and type casting are incorrectly applied to the wrapper object instead of the wrapped camera update.

The issue pointed out by gemini-code-assist is a false positive. The local variable update is already cameraUpdate.cameraUpdate (the unwrapped inner object). The code checks [update isKindOfClass:] which is exactly the same pattern as every other case in the function.

Thank you for the clarification, @benji-farquhar. I appreciate you pointing out that the update variable is already the unwrapped inner object. You are correct that the isKindOfClass: check is consistent with the existing patterns in FGMConversionUtils.m. I have noted this as a false positive.
