ecc::chip: Fix `print_ecc_chip`
...
The ECC test chip performs various checks that assume the chip will only
be synthesized with witnesses. This assumption is broken by the chip
printer test, so we fix the assumption here.

ecc::chip: Define a `MagnitudeSign` type alias
...
This fixes some "complex type" clippy lints, and also will make it
easier to change it to a better-typed struct later.

Remove the `CellValue` type
...
In order to make the changeover easier to review, we redefined
`CellValue<F>` to be `AssignedCell<F, F>`. Now we remove that type and
rename throughout the codebase.

Remove `Var::new` trait method
...
As the underlying `Region` methods now return `AssignedCell` instead of
`Cell`, we can simplify all the places where we then constructed a
`CellValue` struct.

Migrate to halo2 version with `AssignedCell`
...
We change `CellValue` into a typedef of `AssignedCell` to simplify the
migration in this commit.
The migration from `CellValue` to `AssignedCell` requires several other
changes:
- `<CellValue as Var>::value()` returned `Option<F>`, whereas
`AssignedCell::<F, F>::value()` returns `Option<&F>`. This means we
need to dereference, use `Option::cloned`, or alter functions to take
`&F` arguments.
- `StateWord` in the Poseidon chip has been changed to a newtype around
`AssignedCell` (the chip was written before `CellValue` existed).
