Handle remapped paths correctly when generating "Source" links
Fixes https://github.com/rust-lang/rust/issues/150100.
This PR fixes a regression introduced by [#149709](https://github.com/rust-lang/rust/issues/149709), I was overzealous in my changes (https://github.com/rust-lang/rust/pull/149709/changes#diff-e1cf7ef2fb411d24980cd4cbea1e867cc36029e9496e1ceca64cfb6a0e3510f6) and accidentally changed the behavior of `rustdoc` in the presence of remapped, to simply reject them instead of handling them.
With this PR remapped paths are handled correctly, in a similar way as it was before.
~~I added a run-make test to make sure we don't regress it again, a simple `rustdoc` test in not sufficient as `rustdoc` is not called on the auxiliary crate. It's not pretty but it works.~~ https://github.com/rust-lang/rust/pull/150172#issuecomment-3676762399
rustdoc doesn't have any handling for `--remap-path-scope`, so I used the `MACRO` scope (it was already used [elsewhere](
