[GitHub CI] Clear unused NDKs and iOS simulator to fix Android CI
Summary:
This diff does two things:
- Brings back D9464, which was previously removed in D11202
- Implements the changes suggested in this GitHub comment to delete iOS simulators and associated caches
Test Plan: I landed the changes to android_ci.yml directly on master and confirmed that the GitHub Actions run succeeded: https://github.com/CommE2E/comm/actions/runs/10722767078/job/29734470192
