[EuiCombobox][COGNITION]: Combo boxes should open on user interaction instead of focus event

[1Copenut]

Description

A customer raised this as an issue with our sitewide search in Kibana. When users click or keypress navigate to our sitewide search, the combobox opens automatically. This is an issue with Success Criterion 3.2.1: On Focus because we are making a significant change of page context.

Suggested change

Can we explore changing the listbox show event to listen for keypresses like DOWN_ARROW or letters when users start typing? This might be a breaking change item, so happy to discuss further.
