XpsDocumentWriter.SaveAsXaml - BitmapMetadata is not available on BitmapImage

* .NET Core Version: 6.0 (guess all versions)
* Visual Studio 2019, 2022, 2022 preview

**Problem description:**
Attaching WinDbg Preview to a process I see lots of System.NotSupportedException happening with message "BitmapMetadata is not available on BitmapImage"

Why throw instead of checking if metadata is supported or not ?

**Actual behavior:**

`(50e8.3f8): CLR exception - code e0434352 (first chance)
Exception object: 000001f93a3e2b20
Exception type: System.NotSupportedException
Message: BitmapMetadata is not available on BitmapImage.

**Expected behavior:**

Looks like this is by design: https://stackoverflow.com/a/17027474/187650
Though, would be much nicer to see if metadata is supported instead of throwing...
