[image_picker_ios] Re-adds Swift Package Manager compatibility (flutter#6833)

Adds Swift Package Manager compatibility to `image_picker_ios`.

The previous attempt, flutter/packages#6617, was partially reverted due to flutter#148307. This reland uses the new approach proposed in flutter#148572: the Swift Package Manager package does not have a `.modulemap`. As a result, the plugin no longer has a `.Test` submodule if using Swift Package Manager.

Fixes flutter#146919.
