This PR reverts https://github.com/leanprover/lean4/pull/11396, which
changed `set_library_suggestions` to create an auxiliary definition
marked with `@[library_suggestions]`, rather than storing `Syntax`
directly in the environment extension.
It wasn't tested properly.

This PR changes `set_library_suggestions` to create an auxiliary
definition marked with `@[library_suggestions]`, rather than storing
`Syntax` directly in the environment extension. This enables better
persistence and consistency of library suggestions across modules.
The change requires a stage0 update before tests can be restored. After
CI updates stage0, a follow-up PR will restore the test cases.
