refactor: WF.Fix: gather subgoals (#3017) 
This is pure refactoring: Instead of solving each subgoal as we
encounter it while traversing the syntax tree, we leave the `MVar`
there, at the end collect them all using `getMVarsNoDelayed`, and then
solve them.

This is a refactoring preparing for two upcoming changes:

 * removing unexpected duplicate goals that can arise from term
   duplication
 * running interactive tactics on all, not each goal (#2921)

In order to not regress with error locations, we have to associated the
`TermElabM`’s syntax refernce with the `MVar` somehow. I do this using
the existing `mkRecAppWithSyntax` expression annotation, on the `MVar`’s
type. Alternatives would be stack another `StateT` on the traversal
and accumulate `Array (MVarId, Syntax)` explicitly, but that did not
seem to be more appealing.
