BoundingRegion: Tolerance argument in the methods

### Context

Comes from [this ](https://github.com/ToyotaResearchInstitute/maliput_object/pull/7#discussion_r861682305) PR comment.

`BoundingRegion` api doesn't know about tolerance. In the first implementation that we have, `BoundingBox` asks for tolerance in its constructor.

Question is, would it be better to request tolerance only in the methods? This will imply recognizing from the BoundingRegion's api that tolerance is requested when calling the methods.

Probably the most related use-case is that this package in general, `maliput` will be used and when objects are being constructed there won't be possible to call `maliput::api::RoadGeometry::linear_tolerance()` in order to match tolerances, as probably the RoadNetwork won't be ready to be queried yet.

Start by reviewing the discussion linked from PR #7 and the BoundingRegion and BoundingBox APIs mentioned in the issue. Determine whether tolerance belongs in BoundingRegion methods rather than construction, and document the chosen API behavior and matching tolerance expectations as the definition of done.
