new a7765d23766 [fix](nereids) topN filter: use ObjectId as map key

[fix](nereids) topN filter: use ObjectId as map key instead of Topn node
(#46551) (branch-3.0) (#46585)
pick#46551
### What problem does this PR solve?
Plan node is not good to be hash map key, because two plan nodes in
different tree level may be regarded as "equal". for example, in
following tree, topn1.equals(topn2) may be true.
Topn filter generator should distinguish them, and hence topn
node is not suitable to be used as hash map key.
topn1
-->some node
-->topn2
-->other node
