New description:
This patch makes the `FiniteField` constructor call the implementation-
independent code for choosing irreducible polynomials from #14832.
With this patch, the generic constructor always passes an actual
polynomial (not a string specifiying an algorithm to construct one) to the
finite field implementation class. For backwards compatibility, the
existing classes still recognise a string `modulus`. Checking if the
finite field is a Conway polynomial is now done by an implementation-
independent function.
This will be a dependency of #12142.
