[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.
