fix: Remove non-allowed file APIs

[philipphofmann]

📜 Description

Remove usage of NSFileSystemFreeSize and NSFileSystemSize because Apple forbids our usage; see
https://developer.apple.com/documentation/bundleresources/privacy_manifest_files/describing_use_of_required_reason_api?language=objc.

Most of the diffs are generated crash reports.

💡 Motivation and Context

Fixes GH-3590

💚 How did you test it?

Unit tests and a manual test with a simulator.
