Show return type hints for lambdas #15015

Open 0101 opened 1 year ago

Separating this from #14379

It will require some changes to the current type hint system which processes symbol uses - as lambda's don't have a symbol.

We could, for example, report a synthetic lambda symbol at the lambda range. It could also cover function cases. Alternatively, we could report types at ranges and expose it in FCS (the infra is already there, and it's used in member completion).
