Do not gate or hide experimental settings This is somewhat hacky fix just for 2.15. I unintentionally hid them from the manual, when no one wanted to hide them that (including myself). I also required the experimental feature to be enabled in an order-dependent way, which is not good. The simplest fix for this immanent release is just to always show them, and always allow them to be set. Effectively undoes some changes from aa663b7e89d3d02248d37ee9f68b52770b247018

# Skipping these two for now, because we actually *do* want flags and
# config settings to always show up in the manual, just be marked
# experimental. Will reenable once the manual generation takes advantage
# of the JSON metadata on this.

Punt on improper global flags for now See the note in the test. We don't want these flags showing up for commands where they are irrelevant. Eventually, this needs a proper fix, but it need not be a blocker for stabilize: for a quick-n-dirty punt, just put these flags behind the `nix-command` unstable feature. This is fine because they are only relevant for commands which we don't need to stabilize for a while.

Stuctured command stability Prior to this, there was an ad-hoc whitelist in `main.cc`. Now, every command states its stability. In a future PR, we will adjust the manual to take advantage of this new information in the JSON. (It will be easier to do that once we have some experimental feature docs to link too; see #5930 and #7798.)

# These 3 arguments are currently given to all commands, which is wrong (as not
# all care). To deal with fixing later, we simply make them require the
# nix-command experimental features --- it so happens that the commands we wish
# stabilizing to do not need them anyways.
