Auto merge of #86911 - bjorn3:crate_info_refactor, r=petrochenkov

Refactor linker code

This merges `LinkerInfo` into `CrateInfo` as there is no reason to keep them separate. `LinkerInfo::to_linker` is merged into `get_linker` as both have different logic for each linker type and `to_linker` is directly called after `get_linker`. Also contains a couple of small cleanups.

See the individual commits for all changes.
