Overview
The validation context gets passed to each validator.
It exposes a Language::Visitor where validators may add hooks. (Language::Visitor#visit is called in GraphQL::StaticValidation::Validator#validate)
It provides access to the schema & fragments which validators may read from.
It holds a list of errors which each validator may add to.
It also provides limited access to the TypeStack instance, which tracks state as you climb in and out of different fields.
