Rollup merge of #76711 - davidtwco:issue-51154-param-closure, r=estebank

diag: improve closure/generic parameter mismatch

Fixes #51154.

This PR improves the diagnostic when a type parameter is expected and a closure is found, noting that each closure has a distinct type and therefore could not always match the caller-chosen type of the parameter.
