[iOS] Add platform view to integration_test example (#164144)
Adds a platform view that simply renders a blue square to the
integration_test
example, and updates the screenshot capture code to capture all windows,
ensuring that any native picture-in-picture, split views, etc. are
catpured.

Adds a screenshot test that captures the platform view alongside the
existing
test. Improved API for screenshot capture will land in a followup patch.
