[android][core] Add `Map::latLngBoundsForCameraUnwrapped` and jni binding for `getVisibleCoordinateBounds`. (#16069)

* [android] Add getVisibleCoordinateBounds method.
* Fix Map::latLngBoundsForCamera, add Android binding for getVisibleRegionBounds.
* Add unit tests for CameraToLatLngBoundsWithRotation and CameraToLatLngBoundsCrossDateLine.
* Move API breaking changes to a new method name latLngBoundsForCameraUnwrapped.
