feat(tvix/build): don't force outputs to be in store_dir r/7283
There's no need to require builds to also put their outputs in store_dir.

So rename store_dir to inputs_dir and make outputs consume paths, not
basenames.

Also document the possibility for builds to write to inputs_dir. Let's
see if we want to make this a constraint later.
