7912: Dedupe import map results r=matklad a=SomeoneToIgnore While debugging https://github.com/rust-analyzer/rust-analyzer/issues/7902, I've found that there are some duplicates are produced during the external dependencies lookup. I've spotted at least some of the `indexed_value.value` duplicated when typed `Arc` and requested the completions for that, so I've also deduped the `IndexedValue`'s to avoid unnecessary computations. This helps to show `Arc` in the completion suggestions in a zero dependency project and in `hir` module, but we loose it again in the `ide` module.
