Add AccessibilityReportsService class

Part of #211389 (closed)

This feature will be behind a feature flag called accessibility_report_view.

What does this MR do?

This MR adds a new CompareAccessibilityReportsService which will be used in a follow up MR to generate an accessibility report diff on a MR widget.

Standard approach to leverage our generic service comparison to create a diff, similar to other reports such as CompareTestReportsService or CompareDastReportsService.

Why are we doing this?

Step #10 to introduce Accessibility Report comparison with our Merge Request Widget.

The entire feature has been developed on an MVC branch, this MR aims to break it down in smaller chunk.

Reviewer roulette

Changes that require review have been detected! A merge request is normally reviewed by both a reviewer and a maintainer in its primary category (e.g. frontend or backend), and by a maintainer in all other categories.

To spread load more evenly across eligible reviewers, Danger has randomly picked a candidate for each review slot. Feel free to override these selections if you think someone else would be better-suited, or the chosen person is unavailable.

To read more on how to use the reviewer roulette, please take a look at the Engineering workflow and code review guidelines.

Once you've decided who will review this merge request, mention them as you normally would! Danger does not (yet?) automatically notify them for you.
