This reverts commit 4f91e9599f.
This broke:
when I applied this pr, `--print-out-paths` wouldn't print anything:
```
shell-for-nix-env % nix build --print-out-paths .#legacyPackages.aarch64-darwin.homeConfigurations.macos.activationPackage
```
After dropping the patches from my fork, it does again.
```
shell-for-nix-env % nix build --print-out-paths .#legacyPackages.aarch64-darwin.homeConfigurations.macos.activationPackage

```
Fix#11897
As described in the issue, this makes for a simpler and much more
intuitive notion of a realisation key. This is better for pedagogy, and
interoperability between more tools.
The way the issue was written was that we would switch to only having
shallow realisations first, and then do this. But going to only shallow
realisations is more complex change, and it turns out we weren't even
testing for the benefits that derivation hashes (modulo FODs) provided
in the deep realisation case, so I now just want to do this first.
Doing this gets the binary cache data structures in order, which will
unblock the Hydra fixed-output-derivation tracking work. I don't want to
delay that work while I figure out the changes needed for
shallow-realisations only.
This reverts commit bab1cda0e6.

Introduce a new `Signature` struct that represents a cryptographic
signature
along with the key name that produced it. This provides:
- Structured representation instead of colon-separated strings
- Type-safe parsing with `Signature::parse()`
- Serialization with `to_string()`
- JSON serialization/deserialization
- Batch parsing with `parseMany<Container>()`
- Batch serialization with `toStrings()`
This is scaffolding for future changes that will use this type
throughout the codebase.
The test data was using invalid signature strings like "asdf" and
"qwer" which don't follow the required "name:base64signature" format.
This updates them to use properly formatted signatures with valid
base64-encoded data.
This progress on #11896. It introduces some issues temporarily which
will be fixed when #11928 is fixed.
The SQL tables are left in place because there is no point inducing a
migration now, when we will be immediately landing more changes after
this that also require schema changes. They will simply be ignored by in
this commit, and so all data will be preserved.
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.
