What does this PR try to resolve?
This PR fixes issue #10545. The root cause was:
unit_dependenciesattempts to addDocscrapeunits as dependencies of the host-type crate.activated_featuresattempts to lookup(dep, Host)in the feature map, but only(dep, NotHost)exists.The fix is to ensure that host-type crates do not have Docscrape units added as dependencies.
How should we test and review this PR?
