[ResponseOps] [Rule Form] Move rule form steps to hook with progress tracking

[Zacqary]

Summary

Part of #195211

In preparation for the horizontal rule form layout, move the generation of the rule form steps into three hooks:

• useCommonRuleFormSteps: private hook that generates a series of objects specifying the rule form steps, how to display them, and what order to display them in
• useRuleFormSteps: hook that calls useCommonRuleFormSteps and transforms them into data for the standard vertical EuiSteps, along with progress tracking based on onBlur events
• useRuleFormHorizontalSteps: hook that calls hook that calls useCommonRuleFormSteps and transforms them into data for EuiStepsHorizontal, plus navigation functions. These will be used in the smaller rule form flyout in a second PR

Because EuiStepsHorizontal rely more heavily on the EuiSteps status property, I took this opportunity to improve progress tracking in the standard vertical steps. Most rule types will load the create page with Step 1: Rule Definition already being in a danger state, because an incomplete rule definition component immediately sends errors, and the error API doesn't distinguish between invalid data or incomplete data.

This PR wraps each step in a reportOnBlur higher-order component, which will report the first time a step triggers an onBlur event. Steps with errors will now report incomplete until they first trigger an onBlur. The result:

1. The user loads the Create Rule page. Rule Definition is marked incomplete
2. The user interacts with Rule Definition, but does not yet complete the definition.
3. The user interacts with the Actions step, the Rule Details step, or another part of the page. The Rule Definition is now marked danger.

This is inelegant compared to an error API that can actually distinguish between an incomplete form and an invalid form, but it's an improvement for now.
