Migrate to group traits
...
The `Curve` trait is now `CurveExt: group::prime::PrimeCurve`, and
`CurveAffine` is now `CurveAffine: group::prime::PrimeCurveAffine`.
There is no `CurveAffine` trait in `group`, and it's a widely-used
trait in this crate, so we don't rename it to `CurveAffineExt`.

Define hash-to-curve over Curve, not CurveAffine
...
This removes an unnecessary layer of indirection from the type system,
and ensures that these APIs depend on the halo2-specific trait with the
extensions we require.
