This enables chips that e.g. want to load multiple lookup tables into
the same columns to store state about where each table was layed out.

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.
