Mark experimental features on settings

Browse source 
We hide them in various ways if the experimental feature isn't enabled.

To do this, we had to move the experimental features list out of
libnixstore, because the setting machinary itself depends on it. To do
that, we made a new `ExperimentalFeatureSettings`.
