Zcu: allow test declarations to be failed

The introduction of the `extended(astgen_error())` instruction allows a `test` declaration to be unresolved, i.e. the declaration doesn't even contain a `func`. I could modify AstGen to not do this, but it makes more sense to just handle this case when collecting test functions. Note that tests under incremental compilation are currently broken if you ever remove all references to a test; this is tracked as a subtask of #21165.
