refactor(algebra/triv_sq_zero_ext): generalize and cleanup (#10729) This:

• Generalizes typeclass assumptions on many lemmas
• Generalizes and adds missing typeclass instances on triv_sq_zero_ext, most notably the algebra structure over a different ring.
• Reorders many of the lemmas in the file to ensure that the right arguments are implicit / explicit
