## Summary Closes #187089 Fixes the performance of the ES|QL charts: - the panel - the table visualization The ES|QL charts become imperformant for a big amount of fields. I am changing the implementation a bit in order to render (and hold to cache) only the fields that take part in the visualization and not all colums ### Checklist - [ ] [Unit or functional tests](https://www.elastic.co/guide/en/kibana/master/development-tests.html) were updated or added to match the most common scenarios

Describe the bug:
When an ES|QL panel is added to a dashboard with this particular dataset, the browser freezes.
Steps to reproduce:
node scripts/functional_tests_server.js --journey x-pack/performance/journeys_e2e/data_stress_test_lens.tsnode scripts/es_archiver.js --es-url http://elastic:changeme@localhost:9220 --kibana-url http://elastic:changeme@localhost:5620 load test/functional/fixtures/es_archiver/stress_testnode scripts/kbn_archiver.js --kibana-url http://elastic:changeme@localhost:5620 load test/functional/fixtures/kbn_archiver/stress_testExpected behavior:
The browser tab shouldn't crash.
Screenshots (if relevant):
Provide logs and/or server output (if relevant):
Server is as happy as a clam.
Any additional context:
Interestingly, the same issue doesn't occur in Discover ES|QL mode. Just dashboard panels.
