CombinatorialFreeModule's: customizing the order of terms in the output of elements

[nthiery]

As the title says.

By the way, this (partially) refactors sage.misc.misc.repr_lincomb and its use in FreeAlgebra and friends. It also discards some now useless code in symmetric functions.

Depends on #12490

For the record: I had a review patch fixing the doc and checking the input of
CombinatorialFreeModule on sage-combinat queue. Nicolas reviewed it
positively. I'm uploading here everything folded.
