fix(linter): memorize visited block id in neighbors_filtered_by_edge_weight (#3407)

closes: #3396

we visit the same node too many times, I picked some result from run require-render-return rule on [timeserieseexploere.js](https://github.com/elastic/kibana/blob/main/x-pack/plugins/ml/public/application/timeseriesexplorer/timeseriesexplorer.js)
