feat(RingTheory): define two-sided Jacobson radical (#17341)

  • Add a constructor TwoSidedIdeal.ofIdeal to turn an Ideal that happens to be two-sided into a TwoSidedIdeal.
  • Use ofIdeal to define a two-sided version of the Jacobson radical.
  • Generalize some ring lemmas that didn't need to assume commutativity.
