group: Rename into_*(&self) -> to_*(&self)
...
Rust naming convention uses the into_ prefix for methods that consume
self, and the to_ prefix for methods that take an immutable reference.

group: Remove EncodedPoint::from_affine
...
The EncodedPoint trait is replaced by explicit bounds on the
CurveAffine::{Uncompressed, Compressed} associated types.

group: Remove EncodedPoint::{into_affine, into_affine_unchecked}
...
Replaced by explicit APIs on the CurveAffine trait.
GroupDecodingError has been moved into pairing::bls12_381::ec, as it is
no longer used by the group traits.

group: Direct-to-affine CurveProjective::batch_normalize
...
Replaces the mutating CurveProjective::batch_normalization API, and
removes the need for CurveProjective::is_normalized.
The new temporary implementation in pairing::bls12_381::ec is adapted
from bls12_381::g1.

group: Define group operations on Group trait
...
The GroupOps trait represents the group operation (addition), and the
combination of the group operation with group inversion (subtraction).
Group inversion (negation) is constrained directly on the Group trait.

group: Introduce Group and PrimeGroup traits
...
Group represents a cryptographic group with a large prime-order subgroup
and a small cofactor. PrimeGroup further constrains the group to have a
cofactor of one.

Remove Engine associated type from CurveAffine and CurveProjective

The type Curve*::Engine::Fr is equivalent to Curve*::Scalar, making
Engine a redundant associated type.

Remove explicit std::marker from Sized bound
...
Sized is always part of the prelude, and binding on std causes
compilation issues for no-std crates.

ff: Remove SqrtField trait
...
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.
