CmdPal: Manually iterate package metadata tags to prevent exceptions (#45502)

## Summary of the Pull Request

This PR fixes an error that occurred when reading tags for the selected
package in WinGet extensions when AOTed. The issue was caused by using
LINQ over a WinRT proxy; this has been replaced with manual iteration
over the collection to avoid the failure.

The exception is now caught and logged as a warning by #44757.
