[Security Solution][Detections] EQL UX Improvements (#80230) (#80376)

* Add loading spinner to EQL Query Bar

This gives the user some indication that the validation is being
performed in the background, and that their query's validity is
currently undefined.

* Preserve whitespace on display of rule queries

This is useful for all rules, but particularly for EQL rules, where
sequences will be multiline.

* Fix tests around query description

This content is now wrapped in a whitespace-preserving element, so these
need to be updated ever so slightly.

* Update cypress assertions around rule queries

* Remove extra space from assertion
  * This extra space was removed in the presentation component. I didn't
    find an explicit reason why it was there in the first place.
* Use have.value when asserting on form inputs
