Feature request: detect potential API breaking change for Typescript/JS in APIview

Scenario 1:

Select two revisions and diff is shown, along with warnings/errors for potential breaking changes from rev x->y.

Scenario 2:

Pin a API view url as a base (along with its revision) and select a revision from another API view for diff. Then get warnings/errors for potential breaking changes from url a rev x-> url b rev y.

This scenario is for the case Devs are tracking APIs in different api-views or they want to recreate a baseline one because existing apiviews don't represent properly the correct baseline that is released.

Breaking changes:

Warn only initially, so it can be a bit more "aggressive" biasing towards detecting more cases over accuracy (it's fine to warn false-break-changes, that is just to help devs to not miss anything before releasing).
