What does this PR do?

Add a ci step to check ffi-examples in a maintainable way.

Motivation

Realizing after the fact that some examples don't build (let alone pass the tests) on certain platforms.

Additional Notes

I don't know much about github actions, AI did the thing.

How to test the change?

cargo ffi-test locally, or the pipeline of the PR I guess.
