[Fix] Revert removed setTimeout on EuiInputPopover scroll listener

[mgadewoll]

Summary

closes #7761

This PR reverts earlier changes done in this PR which remove a setTimeout on EuiInputPopover's scroll listener.
This change triggered flaky e2e test behaviors in Kibana (observed from version 94.3.0).

QA

Verifying fix on Kibana

1. on EUI side

• checkout this PR: gh pr checkout 7760
• build the package locally in packages/eui with yarn build-pack

2. on Kibana side

• follow the steps listed in this wiki to add the local package to Kibana
• run Kibana locally (yarn es snapshot, yarn kbn bootstrap --no-validate && yarn start)
• navigate to the security_solution test directory and run the cypress tests

cd x-pack/test/security_solution_cypress
yarn cypress:open:ess

• wait until the tests are up and running and choose the test rule_creation/common_flows.cy.ts to run
• verify the test finishes (on the broken version the test hangs when navigating combo boxes and won't finish)
• rerun the test a couple times to be sure it's not flaky

Verifying Firefox issue around unexpectedly closing combobox panel on hover is still fixed

🔗 Issue conversation

• open the tooltips section of the EUI docs for EuiComboBox in Firefox
• click the input of EuiComboBox for opening the popover panel
• hover the option items
• verify the panel stays open

I tested the changes locally and verified it fixes kibana tests. I'm happy to get this merged when Cee's comments are addressed :)

Thanks so much for hopping on this Lene! Also, looking forward to when we can more frequently run EUI against Kibana CI to catch issues like this that only crop up in test environments 😭
