Rollup merge of #80031 - petrochenkov:builtina, r=estebank
resolve: Reject ambiguity built-in attr vs different built-in attr

Fixes https://github.com/rust-lang/rust/issues/79798.

Resolution ensures that inert attributes cannot be used through imports like this, but built-in attributes don't go through initial resolution (only through resolution validation), so we have to keep some extra data (the built-in attribute name) to prevent it from happening.
