Add visibleAnnotations API to make it easier for clients of MGLMapView
to query for all visible annotations in the map or all visible annotations
in a subsection of the map.
Use common initialization logic to create an unique pointer to an mbgl
source object, up front, when a MGL source is created. Keep a raw
pointer to the unique pointer that is pointed at the mbgl source
instance when a MGL source is created or when a MGL source is
obtained by identifier from MGLStyle. Once the transfer of ownership of the
mbgl source takes place, the unique ptr is null. The raw pointer can be used
internally for future work that involves mutating the source.
This also changes the URL, features, and geoJSONData content
properties for MGLGeoJSON source to be writable. If they are set with
valid data after a source has been added to the map then the map will
update to reflect the new data.
MGLStyleConstantValue and MGLStyleFunction now inherit from MGLStyleValue with a generic argument matching the child class’s own generic argument.

To obtain precise results, we:
1. Round scale value to obtain same results from symbol shader.
2. Generate a boost geometry polygon to check if it intersects()
against all feature boxes.
3. Check if current scale is within each feature's minimum and maximum
placement scales.
4. De-scale feature boxes when intersecting to account for the
fractional zoom scaling.
* [ios, macos] Introduce MGLPointCollection
This makes MGLMultiPoint abstract again so that it is only a place
for shared functionality of polygons and polylines. The multipoint
feature replaces the point collection feature and can be
used to initialize a MGLGeoJSONSource. The previously added
swift_names for polyline and polygon are removed, for now.
This also updates the iOS and macOS annotation adding logic so that
unwanted shapes really are avoided. Previously the combined OR
conditions meant that an annotation had to logically be NOT a kind
of all three types so the check always let the annotation slip through.
This also expands the guard to deflect the new MGLPointCollection.
* [ios, macos] Make feature attributes and identifier writable
Instances of MGLFeature subclasses can now have their attributes
and identifier properties mutated.
Implement the layer property on MGLStyleLayer itself, where it’s declared, so that the check for an abstract style layer doesn’t itself raise an exception. The concrete style layer classes still declare their own layers as covariant properties, although those properties aren’t actually used anywhere.
