Tooltip could crash during runtime because of `preconditionFailure()`

Environment Information

• Platform:
  • iOS: any
  • macOS: any
• Package version(s): (fill this out, include which package manager you're using): latest
• Xcode and OS versions: (fill this out if relevant): any version supported

Please provide a reproduction of the bug:

The anchorView's window can be nil when it got removed from the view hierarchy.
In this situation, preconditionFailure() will lead to runtime crash.

Since Tooltip isn't a critical UI for most business logic, should we crash the app when this exception happens?

I searched for preconditionFailure() in this repo (https://github.com/microsoft/fluentui-apple/search?p=1&q=preconditionFailure) and found that most of its use is for unimplemented initializers.

Actual behavior:

Tooltip could crash the app.

Expected behavior:

This UI component shouldn't crash app. Or at least, we can have an alternative to crash (runtime error log?)

Priorities and help requested:

Are you willing to submit a PR to fix? No. Or yes if we have a clear path to fix it.

Requested priority: Normal

Search the Tooltip implementation for preconditionFailure and inspect the anchorView/window handling; reproduce the case after the view leaves the hierarchy. Done means the component no longer crashes in that situation and the chosen alternative behavior is covered by a test.
