Remove UIDeviceIdentifier dependency from WordPressKit

[kean]

The dependency was used in a single line: UIDeviceHardware.platform(), so it wasn't worth requiring it in the framework. Instead, I added it directly to the app.

I tested the before/after on a physical device, and the value was unchanged, so no manual testing needed.

UIDeviceIdentifier was also a transient dependency, so I moved it to the Podfile to fix it for now. The only remaining place that uses it is Automattic-Tracks-iOS.

  - Automattic-Tracks-iOS (3.3.0):
    - Sentry (~> 8.0)
    - Sodium (>= 0.9.1)
    - UIDeviceIdentifier (~> 2.0)

Automattic-Tracks-iOS seems to support SPM, so WPKit should no longer block us from adding Automattic-Tracks-iOS as a Swift package.

PR submission checklist:

• [ ] I have completed the Regression Notes.
• [ ] I have considered adding unit tests for my changes.
• [ ] I have considered adding accessibility improvements for my changes.

Testing checklist:

@jkmassel I rebased and re-implemented this PR. Instead of injecting platform from the app, I implemented this tiny extension inside the framework. It achieves the same result: the UIDeviceIdentifier framework is no longer linked dynamically and WordPressKit has fewer dependencies.
