VHDL-2019: Relax Library Requirement on Configurations (LCS-2016-023)

The VHDL-2019 test file tb_023.vhd does not contain a valid test.

I am unsure how to test this one. The modification is that configurations are no longer required to be in the same library as the architecture that instantiates them. So I need to create a configuration in one library, and the test entity in another - then ensure that the configuration can be applied correctly.

This will require multiple files, and is a little more involved of a test than what's currently being run.

Is there any guidance on how we might want to accomplish this?
