Possibility to omit file breakdown

[yamal-coding]

What has changed

Possibility to omit file breakdown from the report. That includes, list of files for each component and dynamic feature, file type and resource type distribution charts, and all ownership info regarding files.

This is an optional feature that can be enabled by activating a flag in the Ruler Gradle config:

ruler {
    omitFileBreakdown.set(true) // false by default
}

The only change in the JSON format of the report is that files field inside each component or dynamic feature is now nullable.

Why was it changed

A first and similar attempt to omit file information was proposed in #101, where only the list of files for each file container was omitted. However, that implied several changes on the format of the report and more complexity. After having received some feedback from @simonschiller , we have agreed that it could be a bit confusing to keep file charts and ownership file info if there isn’t a list of files that can back up that data.

On the other hand, my initial motivation behind this change was to provide a way to reduce the report size. We can’t completely get rid of the list of files because that is something necessary if we want more detailed reports. But we should have the opportunity to generate lighter reports in case that extra information is not required at some point.
