That they are all ordered inside the module and not more private than the module itself.

The import_decl_vis logic is also reused when reporting ambiguous_import_visibilities lint.
Some asserts are hardened.
Some relevant tests are added.

Extracted from #154149.

Finished benchmarking commit (89a90f3): comparison URL.

Overall result: no relevant changes - no action needed

Benchmarking means the PR may be perf-sensitive. It's automatically marked not fit for rolling up. Overriding is possible but disadvised: it risks changing compiler perf.
