Subject: [PATCH] [ios_platform_images] Add integration tests

Currently there are no end-to-end tests for this package that would fail
if the communication with the native implementation didn't work, or if
the native implementation were broken. This is especially problematic
since we want to convert this plugin to both Swift and Pigeon, each of
which has the potential to break things that would currently not be
caught.

This adds basic integration tests of both methods to ensure that the
simple case of a successful call works as expected.
