[Data UI] [Fleet] Add submitOnBlur functionality to QueryStringInput

[Zacqary]

Summary

Fixes an issue identified in #92853 (comment)

This adds a prop called submitOnBlur to the QueryStringInput component. When true, the component will trigger its onSubmit event when the user clicks or tabs away from the component, instead of requiring them to press Enter to make it happen.

Note that this doesn't simply rely on the base onBlur function, as using the mouse to interact with the autocomplete dropdown will momentarily trigger onBlur. Instead, it waits 200ms to make sure the query string <textarea> element has not been re-focused, to ensure that the onBlur was actually the result of an intentional user blur of the element.

API Docs are updated by this PR. This is a minor change.

This LGTM

I worked on some bugfixes in that area and in pending pr adding a hook where I think, submitOnBlur will be ideal: https://github.com/elastic/kibana/pull/94148/files#diff-9c21b61183abad2b8d078185afa822ec12ff2237a3dfe9b0bf09880028528f39R514-R518

I also unskipped tests of that component, so it would be possible to add a test here.

If it is not time pressing, we could wait a bit with this pr until #94148 goes through.
Up to you. Otherwise, I'll merge master and will likely move that handler into the new scheduleOnInputBlur

Fleet changes 🚀 it works as expected

@Dosant I think I want to get this merged just so it's not waiting in the PR queue for a while. Let me know if you need any help merging it with #94148
