ff: Rework BitIterator to work with both u8 and u64 limb sizes
...
This enables BitIterator to be used with both the byte encoding and limb
representation of scalars.

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.

Renamed to Field::pow_vartime to indicate it is still variable time with
respect to the exponent.

WARNING: THIS IS NOT FULLY CONSTANT TIME YET!
This will be fixed once we migrate to the jubjub and bls12_381 crates.

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.

The ff_derive, pairing, zcash_primitives::jubjub, and bellman dummy_engine
changes are minimally implemented on top of the existing *_assign()
functions.
