This generalizes from Algebra.lsmul R M : A →ₐ[R] Module.End R M to Algebra.lsmul R S M : A →ₐ[R] Module.End S M.

This generalization was previously not possible because Module.End S M was not an R-algebra.

Notably this now allows things like Algebra.lsmul R A A : Aᵐᵒᵖ →ₐ[R] Module.End A A (right multiplication).

This doesn't bother attempting to generalize uses in downstream files, as most of them probably do not need the generality. Instead, we just replace Algebra.lsmul R with Algebra.lsmul R R.
