Split out UnkeyedRealisation from Realisation

Browse source 
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`   |
