feat: disallow alternatives of the form | _ ids => ...
...
@Kha We are still accepting wildcard alternatives of the form
`| _ => ...`
It is useful when we can discharge many alternatives using the same
tactic, and it looks like the wildcard alternative used in "match"-expressions.

feat: refine refine tactic
...
Now `refine stx` reports an error when there are natural unassigned
metavariables after we elaborate syntax `stx`. The idea is that only
synthetic holes `?<hole-name>` become new goals.
The tactic `refine! stx` implements the Lean3 behavior.
