[file_selector] Implement canCreateDirectories on macos and linux (#10443)

Updates macos and linux `file_selector` platforms to implement the new `canCreateDirectories` parameter from platform interface

Until now, only macos and linux are able to override this parameter

This is the "platform implementations" step for #9965

Part of: flutter/flutter#141339

## Pre-Review Checklist

**Note**: The Flutter team is currently trialing the use of [Gemini Code Assist for GitHub](https://developers.google.com/gemini-code-assist/docs/review-github-code). Comments from the `gemini-code-assist` bot should not be taken as authoritative feedback from the Flutter team. If you find its comments useful you can update your code accordingly, but if you are unsure or disagree with the feedback, please feel free to wait for a Flutter team member's review for guidance on which automated comments should be addressed.

[^1]: Regular contributors who have demonstrated familiarity with the repository guidelines only need to comment if the PR is not auto-exempted by repo tooling.
