This marks every identifier used within an attribute as seeds. The scenario this avoids is functions referenced through attributes on unused tables or record types (&default, &expire_func, ...) being dinged as unused as that's rather confusing. Also adds test for the above and a light smoke test into language/ as it doesn't appear we had coverage here. Closes #3122

# @TEST-DOC: Usage analyzer marked lambdas and functions in attribute expressions of unused tables or record types as unused. That is a bit confusing. Regression test for #3122.
