Fix typo in primops.cc (and therefore Nix docs)

Make `StoreConfig::getDefaultSystemFeatures` a static method

This also fixes the typo in the Nix docs at https://nixos.org/manual/nix/unstable/language/built...

This makes something in Hydra bit simpler. If someday the default

Make `Machine::systemTypes` a set not vector

There's just enough logic (the `"builtin"` special case) that makes this
worthy of its own method.

This is more conceptually correct (the order does not matter), and also
matches what Hydra alrea...

Document JSON formats
