Replace Xamarin.Cache.CreateTemporaryDirectory() with a local helper that uses NSFileManager.TemporaryDirectory

  • Path.GetRandomFileName().

This is because Cache.CreateTemporaryDirectory() might create a path inside the current
app bundle, which breaks incremental builds (they won't sign correctly).

Pull request overview

This PR updates the macOS FSEventStreamTest to stop using Xamarin.Cache.CreateTemporaryDirectory() (which can create directories under the app bundle and break incremental build signing) and instead create temporary directories under the system temp directory, with symlinks resolved to match what FSEventStream reports.

Changes:

  • Added a local CreateTemporaryDirectory() helper that creates a directory under NSFileManager.TemporaryDirectory.
  • Resolved temp directory paths via realpath to match FSEventStreamCopyPathsBeingWatched canonicalized paths.
  • Replaced Xamarin.Cache.CreateTemporaryDirectory() call sites in this test with the new helper.
