Add an option to restore per-source collision detection

Implement the equivalent of mapbox/mapbox-gl-js#6566 in gl-native

Add an option to restore collision detection behavior from before cross-source collision detection (#10436)

[1ec5]

Just a reminder that point annotations should never be hidden due to symbols in other sources, regardless of the option that would be introduced for this issue. Otherwise, we’ll regress #10845.

I don't think this will have anything to do with #10845, since point annotations use "icon-allow-overlap": true under the hood. At any rate, if people change this option from the default, the result is to show more symbols, not fewer.

Fixed in Node and Android with #12842. iOS is ticketed at #12847.
