Move package to @mapbox namespace.

[lucaswoj]

Thanks @tmcw & @tmcw's bash scripts.

I think this is the workflow we'll need to get this change pushed all the way through. Anything missing here?

Todo

• [ ] 🚢
• [ ] publish this package in @mapbox namespace
• [ ] deprecate the old non-namespaced package
• [ ] update all internal projects that reference mapbox-gl-style-spec

[mourner]

How about removing the mapbox- prefix for less redundancy? E.g. @mapbox/gl-style-spec instead of @mapbox/mapbox-gl-style-spec.

[jfirebaugh]

If we do that, we should remove gl too.

[mourner]

@jfirebaugh should we also publish GL JS under @mapbox/js, or should it still be @mapbox/gl-js?

Planning to do this at the same time as https://github.com/mapbox/mapbox-gl-js/issues/3794

Rolling this into mapbox/mapbox-gl-js#3794 and https://github.com/mapbox/mapbox-gl-js/pull/3946
