Pierre Bourdon d84ff32ce6 hydra-eval-jobset: Use nix-eval-jobs instead of hydra-eval-jobs
incrementally ingest eval results

nix-eval-jobs streams output, unlike hydra-eval-jobs. Now that we've
migrated, we can use this to:

1. Use less RAM by avoiding buffering a whole eval's worth of metadata
   into a Perl string and an array of JSON objects.
2. Make evals latency a bit lower by allowing the queue runner to start
   ingesting builds faster.

Also use the newly-restored constituents support in `nix-eval-jobs`

Note, we pass --workers and --max-memory-size to n-e-j

Lost in the h-e-j -> n-e-j migration, causing evaluation to always be
single threaded and limited to 4GiB RAM. Follow the config settings like
h-e-j used to do (via C++ code).

`nix-eval-jobs` should check `hydraJobs` and then `checks` with flakes
