feat(tvix/value): implement nested attribute set literals r/4455
With this change, nested attribute sets can now be created from
literals.

This required some logic for dealing with cases where at a deeper
nesting point a literal attribute set was constructed from an
optimised representation.

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.
