I found myself wanting these in #25141 We already have some of these results with inconsistent names elsewhere; for now this just adds crosslinks, we can unify the names later. The names are a little inconsistent here; for the domain we have: * `LinearEquiv.multilinearMapCongrLeft` (new in this PR) * `AlternatingMap.domLCongr` * `ContinuousLinearEquiv.continuousMultilinearMapCongrRight` * `ContinuousLinearEquiv.continuousAlternatingMapCongrLeft` * `ContinuousLinearEquiv.continuousAlternatingMapCongrLeftEquiv` (not a linear equiv) and for the range: * `LinearEquiv.multilinearMapCongrRight` (new in this PR) * `LinearEquiv.alternatingMapCongrRight` (new in this PR) * `ContinuousLinearEquiv.continuousMultilinearMapCongrRight` * `ContinuousLinearEquiv.continuousAlternatingMapCongrRight`

We already have some of these results with inconsistent names elsewhere; for now this just adds crosslinks, we can unify the names later.
The names are a little inconsistent here; for the domain we have:
