ff: Move pow_vartime back into Field trait
...
The only places we don't use constant u64 limbs, we use PrimeField::char
instead (except in a single test where we use a field element).

ff: Move pow_vartime into a trait that is generic over the limb size
...
The trait is implemented by default for u8 and u64, allowing pow_vartime
to be used with both the byte encoding and limb representation of field
elements.

Improve Field::pow API and impl
...
Renamed to Field::pow_vartime to indicate it is still variable time with
respect to the exponent.

Constant-time field inversion
...
WARNING: THIS IS NOT ACTUALLY CONSTANT TIME YET!
The jubjub and bls12_381 crates will replace our constant-time usages,
but we NEED to fix ff_derive because other users will expect it to
implement the Field trait correctly.

Move Field operations to operator-backed traits
...
The ff_derive, pairing, zcash_primitives::jubjub, and bellman dummy_engine
changes are minimally implemented on top of the existing *_assign()
functions.
