Subject: [core] Implement Expression::serialize() Issue #10714 - Each
 expression stores its operator as a string, and default serialization is
 [operator, serialize(child1), ...] - Custom implementations of `serialize`
 for Expression types that don't follow the pattern - expression::Value ->
 mbgl::Value converter - node_expression bindings to expose `serialize`
