870939ab03 Implement ec_gpu:GpuField for Fp/Fq
This commit introduces a new feature called "gpu", which enables an
`ec_gpu:GpuField` implementation of `Fp` and `Fq`. This enables the
field arithmetics to be run on a GPU.

The code to convert from a u64 to a u32 vector was taken from
07a84f9727/src/lib.rs (L102-L108)

We also move this dependency behind the `alloc` feature flag, as it is
only required for `crate::hashtocurve`.

f874d29238 Remove FieldExt::rand
This removes a dependency on the `getrandom` crate in no-std mode, which
doesn't work on some no-std targets that `getrandom` doesn't support.

ab03c3d5e1 Remove field traits from behind std feature flag
Now that we have a default implementation of `SqrtRatio::sqrt_ratio`, we
can use it and `FieldExt` in no-std environments.

We introduce an `alloc` feature flag to form a common feature dependency
between `std` and `sqrt-table`. It is currently unused directly, but
will be used after `CurveAffine` is refactored to remove the `std`
dependency.

Closes zcash/pasta_curves#25.

314b1bcb94 Place SqrtTables behind a sqrt-tables feature flag
This enables the crate to be compiled without the tables, instead using
a simple fallback for `SqrtRatio::sqrt_ratio`.

32cc10db46 Move FieldExt::get_lower_32 to SqrtRatio trait
It is only used internally by the table-based square root impl, and we
should probably refactor this further, but for now it can live in the
sqrt extension trait.

3a6f71d2f0 Remove FieldExt::{from_bytes, read, to_bytes, write}
- `ff::PrimeField::{from_repr, to_repr}` are direct replacements for
  `FieldExt::{from_bytes, to_bytes}`.
- `FieldExt::{read, write}` were added for reading and writing `halo2`
  proofs, but `halo2::transcript` now handles this internally.

aeda766c34 Remove FieldExt::ROOT_OF_UNITY
We can use the `ff::PrimeField::root_of_unity` method everywhere we
currently use this associated constant. If there is a more general
need for accessing this as an associated constant, we should consider
that for `ff::PrimeField`.
