…ilinearMap (#10758) This PR adds a coercion from any instance of `SemilinearMapClass` to `SemilinearMap`. This is the standard practice for other parts of the library, such as ring homs (see also the recent change #10368). I also expect this change will help with some rough edges in #6057. Previously, a coercion from `f : AlgHom` to `LinearMap` would look like `f.toNonUnitalAlgHom.toDistribMulActionHom.toLinearMap`, now it should look like `SemilinearMapClass.semilinearMap f`. The new coercion instances are `CoeHead` since the left hand side is a free variable `F`. I redefined the existing `DistribMulActionHom → LinearMap` coercion in terms of the `SemilinearMapClass` coercion to ensure we don't get any diamonds.
