This ticket:
- Implements the option `sparse` for
`CombinatorialFreeModule.Element._vector_`
- Implements `Modules.WithBasis.FiniteDimensional.ParentMethods.matrix`
for building a matrix from a list of elements
- Refactors `Modules.WithBasis.FiniteDimensional.MorphismMethods.matrix`
to use the latter and accept the option `sparse`
This is a follow up to #11111.
It's based on #16659 due to a trivial syntactic conflict. Since #16659
is likely to be positive reviewed very soon, it's probably not worth
it making it independent.
