[ftr] add first-class support for playwrite journeys

[spalger]

Fixes #140676

This PR enables the FTR to load a custom "journey" format config file (example). This config file format is a big iteration on the FTR config file format, but using the @kbn/journeys package can be converted into the components necessary for journeys to behave like standard FTR configs, meaning that journeys can be defined cleanly and in a focused way without making major changes to the FTR or creating a new test runner.

For a comprehensive example of how journeys look in this new format, checkout x-pack/performance/journeys/web_logs_dashboard.ts.

In addition to improving the ergonomics of journeys this PR ensures that failed steps trigger failures, something that wasn't happening before. This requires that journeys are very stable, so the stability of existing journeys was improved and debugging was improved in this PR by adding screenshots taken at the end of each step to failure reports and ensuring that these reports are uploaded in hourly SUPT jobs (example)

Sorry about that @dmlemeshko, my migration of the config file to not need the removed base.config.js file wasn't good, looks like I've got it working now though.

Thank you @spalger, I retested and scalability run works perfectly now
