vector layer: Refactor style.cpp to work with latest style specification #218
Description
The latest maplibre style spec uses some expressions that our cpp code cannot correctly parse. It is fine for now since all our stylesheets we have are using the older specification, but we should update to the newest spec eventually:

command to upgrade stylesheet to latest version:
npm install @maplibre/maplibre-gl-style-spec --global
gl-style-migrate bright-v7.json > bright-v8.json
