For representation wrappers that are used to control the visibility of
type internals, this ensures that the wrapper does not increase the
size of the type.
In practice, the optimiser likely does this anyways but it is good to

For example, this is valid Nix code:
```nix
{
a = {}; # creates optimised empty representation
a.b = 1; # wants to add a `b = 1` to it
b = { name = "foo"; value = "bar"; }; # creates optimised K/V repr
b.foo = 42; # wants to add an additional `foo = 42`
}
```
In these cases, the attribute set must be coerced to a map
representation first which is achieved by the new internal
NixAttr::map_mut helper.

These are a bit tricky to implement because Nix technically treats
them as identifiers, and only if the identifier is not explicitly
overridden within the scope does it yield the expected literal values.
Note that weirdness even occurs with scopedImport.

Implements simple arithmetic operations (+, -, *, /).
There is some scaffolding included to pop and coerce pairs of numbers,
as the Nix language will let arithmetic operators apply to arbitrary
pairs of number types (always resulting in floats if the types are
mixed).

We are going to have a 1:1 drop-in replacement for the old-style nix
tools, and this starts implementing the cli parser part.
The first step is to have a simple integration test suite that can
verify that we match the nix CLI.
clap is a super complicated parsing library, but looking through the
rest they are either too opinioated to be of use for us, or depend on
clap as implementation.
