Hamish Mackenzie 4c8bbbd3ed Add flake.variants (#1661) ...

* Add flake.variants

This allows flakes to easily include variations of the
project by with different project arguments.
Anything you can pass to `project.addModule` can be used.
For instance to include variants using ghc 9.2.4:

```
flake.variants.ghc924.compiler-nix-name = pkgs.lib.mkForce "ghc924";
```
Then use it with:

```
nix build .#ghc924:hello:exe:hello
```

This change also:

* Exposes add `combineFlakes` and `rawFlake` for more control over how flakes are combined.

* Includes package coverageReports to the `hydraJobs` of the flakes.

* Tries to make the materialisation concurrency test more reliable
