Realisations are conceptually key-value pairs, mapping `DrvOutputs` (the
key) to information about that derivation output.
This separate the value type, which will be useful in maps, etc., where
we don't want to denormalize by including the key twice.
This matches similar changes for existing types:
| keyed | unkeyed |
|--------------------|------------------------|
| `ValidPathInfo` | `UnkeyedValidPathInfo` |
| `KeyedBuildResult` | `BuildResult` |
| `Realisation` | `UnkeyedRealisation` |

Fewer macros is better!
Introduce a new `JsonChacterizationTest` mixin class to help with this.
Also, avoid some needless copies with `GetParam`.
Part of my effort shoring up the JSON formats with #13570.
