docs(reference): place objects in ibis when possible

Now random shows up as `ibis.random` instead of `ibis.expr.api.random`.

Some of these objects fail to be found if they are put under ibis,
so they have to stay under ibis.expr.api. This seems to be if the object is defined
statically in the module, rather than imported from another module.
than dynamically
such as
`ifelse = _deferred(ir.BooleanValue.ifelse)`

Maybe deal with that later, but at least improve things for now.

Also, don't specify the package at higher levels of the module,
only at the lowest common
denominator.
There is no visibale change to this, just less code.
