Renderer Modularization PRs

The new Modularized renderer architecture based on Drawables is being merged. The topic/drawable will be merged into topic/drawable-reviewed. The last improvement and fixes will be made on this branch, and then we will merge the changes into main. The legacy renderer pass will remain active until the Drawable renderer pass is stable enough. At that point, we will flip the switch and eventually the legacy renderer code will be removed. If you are interested in following along or make code reviews, please see an overview of the relevant PRs on GitHub.

We are now running an iOS render test on an a real iOS device for every PR. Thanks to the credits we have from AWS this is possible. You should be greeted with a green checkmark from your friendly MapLibre Native Bot when making a PR:
