[core] geometry@0.8.0 / geojsonvt@6.0.0 (#5514)

* [core] geometry.hpp 0.8.0

* geojsonvt @ 6.0.0

* Update platform deps, build scripts

* Perf optimizations/cleanup

* Rebase in geometry@080

* D.R.Y. etc

* Ensure fill annotation geometries have closed rings.

* Optimizations

* Update to geojsonvt @ 6.1.0 for clean handoff between geojson parsing and geojsonvt

* Apply close multi/poly geoms for line annotations as well
