This also removes duplicated inheritance and one of them specifying the wrong field.
Returning a `&String` is unusual but this keeps things easier on both sides.
This will make it easier to evaluate what needs to be resolved in the future.
We can't have validation depend on `TomlManifest::resolved_lints` yet because we need to pull out the resolving of deps first.
Normally, I prefer directly constructing something but I feel this works better in this case so I can limit a lot of work that is coupled to a `package` being present. Since we still directly construct, just with `None`, I think this still works.
I'm somewhat tempted to flatten the function call. The parallel between the package an virtual-manifest cases would help to keep them in sync.

What does this PR try to resolve?
This builds on #13664 and #13666. Currently, once we have deserialized
Cargo.toml, we pass it to a large machinery (to_real_manifest,to_virtual_manifest) so thatCargo.tomlis resolvedSummaryis createdManifestis createdThis splits out the resolving of
Cargo.tomlwhich is mostly workspace inheritance today.While splitting logic conjoined like this can be a bit messy in the short term, the hope is that overall this makes the logic easier to follow (more condensed, focused sections to view; more explicit inputs/outputs).
In particular, I hope that this will make it clearer and easier to shift more logic into the resolving step, specifically the inferring of build targets for #13456.
How should we test and review this PR?
This is broken up into very small steps in the hope that it makes it easier to analyze a step.
