UxmlElements not supported when using DLLs
How to reproduce:
1. Open the attached "IN-85035" project
2. Open the UIBuilder window and observe the “Custom Controls (C#)” drop-down menu under the Library section
3. Open the “MyLibrary” directory under Project files and observe the “TestVisInLibrary.cs” file
Expected result: TestVisInLibrary.cs is visible using the UIBuilder window inside the Editor
Actual result: UxmlElements inside DLLs are unsupported, making TestVisLibrary.cs invisible in the UIBuilder window
Reproducible in: 2021.3.44f1, 2022.3.48f1, 6000.0.21f1

Resolution Note:
The information provided in the Discussions thread is the way to support the code generated for serialization in DLLs. The code generator needs to run during the DLL compilation process. We plan on adding a documentation page in the manual to make this information more available and we will add versioning on UxmlSerializedData to help detect some issues with generated code.
