dennis zhuang 8e45809b6d perf(query): check Substrait encodability once per plan (#9095) ...

`PlanRewriter::should_expand` encoded every node it ascended past to
Substrait. Each call clones the plan, runs an analyzer over it and builds
a fresh `SessionState` with all default features, so a deep PromQL plan
pays that cost once per level.

Encode the root once in `PlanRewriter::new` and skip the per-node call
when it succeeds. `to_substrait_plan` recurses from the root to the
leaves, and `should_expand` only receives sub-trees that `f_down` pushed
on the stack untouched, so a root that encodes proves the whole descent
encodes. A root that does not encode falls back to the per-node check,
which is what locates the node that has to stay on the frontend.
