collect doc alias as tips during resolution

[bvanjoi]

Close #124273

Collect the symbol in the doc alias attributes and provide a tip when a match is found.

In general I'd prefer to maybe not do this at all for the local crate.
It will simplify things and avoid doing work on a good path.
The crate authors are the same people who write the doc alias attributes, so these hints are unlikely to be useful for them.

Agree and accept this suggestion.
