Upgrade default styles to v11

[1ec5]

When version 11 of the Mapbox Streets style and other Mapbox-designed styles are released, the following constants will need to be updated:

mapbox-gl-native/platform/default/mbgl/util/default_styles.hpp

Lines 16 to 21 in 2d527c2

	constexpr const DefaultStyle streets = { "mapbox://styles/mapbox/streets-v10", "Streets", 10 };
	constexpr const DefaultStyle outdoors = { "mapbox://styles/mapbox/outdoors-v10", "Outdoors", 10 };
	constexpr const DefaultStyle light = { "mapbox://styles/mapbox/light-v9", "Light", 9 };
	constexpr const DefaultStyle dark = { "mapbox://styles/mapbox/dark-v9", "Dark", 9 };
	constexpr const DefaultStyle satellite = { "mapbox://styles/mapbox/satellite-v9", "Satellite", 9 };
	constexpr const DefaultStyle satelliteStreets = { "mapbox://styles/mapbox/satellite-streets-v10", "Satellite Streets", 10 };

The style versions have also been hard-coded elsewhere; see #6301 for pointers.

#13585 and #13615 landed so I think we're good to close here.
