ff_derive: Generate modulus representation with correct endianness
...
Now that PrimeField::ReprEndianness exists, users can obtain a
known-endianness representation from the output of PrimeField::char
(which is a PrimeField::Repr, and should return a representation with
the same endianness as PrimeField::into_repr).

ff: Remove Ord bound from PrimeField
...
ff_derive still implements Ord and PartialOrd for the fields it
implements, because pairing::bls12_381 internally assumes that those are
implemented. Once we delete that implementation, we will remove the Ord
and PartialOrd implementations from ff_derive.

ff: Add PrimeField::ReprEndianness associated type

This enables generic code to reliably operate on the bits of an encoded
field element, by converting them to and from a known (little)
endianness.
The BitAnd and Shr bounds on PrimeField are now removed, as users can
perform these operations themselves as needed.

The sqrt() function is now part of the Field trait. ff_derive returns an
error on fields for which it does not support generating a square root
function.
Note that Fq6 and Fq12 in pairing::bls12_381 leave the function
unimplemented. They will be dropped once the migration to the bls12_381
crate is complete. The equivalent structs in that crate are not exposed.
