Return original geometry for GeoJSON features in queryRenderedFeatures

Nobody has claimed this yet.

## Motivation

Consider https://jsfiddle.net/w9bs8jot/. A GeoJSON Line feature is cut into multiple tiles and makes it impossible to query the entire line feature. A customer recently flagged this issue because they wanted users to be able to click on a line feature and get its start and/or end points.

## Design Alternatives

There's a potential workaround.

```
const selectedFeatures = map.queryRenderedFeatures(point);
selectedFeatures.forEach(feature => {
const source = map.getSource(feature.source);
// filter for the feature's original coordinates in the source
console.log('source data: ', source._data.features[0].geometry.coordinates);
})
```

## Design

We could add the original geometry to the features in a GeoJSON vector tile, although this may not be performant enough with large GeoJSON features.

Alternatively, queryRenderedFeatures needs a way to retrieve the original geometry for the feature.

Start with the linked JSFiddle and the queryRenderedFeatures API behavior described in the issue. Investigate how GeoJSON Line features are split across vector tiles and determine a design that lets callers retrieve the original geometry; done means a queried feature exposes the complete source geometry without making large features impractical.
