feat: weight lazy discriminator tree results early matches (#3818) 
The matches returned by the lazy discriminator tree are partially
constrained by a priority, but ties are broken by the order in which
keys are traversed and the order of declarations.

This PR changes the match key traversal to use an explicit stack rather
than recursion and implicitly changes the order in which results are
returned to favor left-matches first e.g., given the term `f a b` with
constants `f a b`, and a tree with patterns `f a x -> 1` `f x b -> 2`
that have the same priority, this will return `#[1, 2]` since the early
matches for the key `a` are returned before the match for `x` which has
a star.

This appears to address the [lower quality results mentioned on
zulip](https://leanprover.zulipchat.com/#narrow/stream/428973-nightly-testing/topic/Mathlib.20status.20updates/near/429955747).
