[Reporting/Screenshotting] Backport screenshotting plugin to 7.17

[tsullivan]

This issue is to backport #120110 to the 7.17 branch.

Why we want to do this: in keeping Puppeteer and Chromium up-to-date to support Kibana Reporting, we routinely spend a lot of time re-doing the Puppeteer changes in the 7.17 branch. Due to #120110 not having been backported, the changes from main can't easily be carried back.

Backporting #120110 to the 7.17 branch will allow us to move more quickly on keeping Chromium and Puppeteer up-to-date.

I explored the feasibility of re-implementing the same change to main that split out the screenshotting functionality from Reporting plugin. Doing a change like this in 7.17 is prohibitively complex, as the screenshotting plugin has binding with Kibana build tasks. It is also complex for other reasons, as it has a "public" layer of code, it includes translations, test helpers, and mocks.

I investigated the extent we can ease the headache of manual backport by looking at the types of changes we currently manually backport when Chromium is updated. Example.

1. The paths.ts and args.test.ts files have a different location in main and 7.17.
2. We should move paths.ts, args.test.ts and args.ts files to a new package.
3. Implement the package in main and 7.17 so that the files have the same location in both branches.

While this will ease the headache of manual backports, it won't solve it. For every backport there also is a change to the yarn.lock file and manual backports will be required there.
