Add options to provide drush analyze output in JSON and CSV

Adding patch for 4.0.0

The patch is working as expected.
Is much easier and faster to find the issues.

Hello, I also tested the #2 patch on 4.0.0 and it works. I was able to output a json file, +1 for RTBC

Why not add both JSON and CSV then? Also there is already the checkstyle output and the ascii output, but they are done in different methods? Why integrate this one in a single method?

I've been looking at how to integrate this more seamlessly. There is also ✨ Add UI option to export Upgrade Status results as CSV Needs review which adds CSV on the UI. It has different logic from your setup and more involved in how it build the data. I think a middle ground would be good as well as ideally as much code reuse as possible between the output formats IMHO.

And there is also ✨ Support generating Code Quality JSON reports (for Gitlab) Needs review .
