Extend :global-exports to auto-alias and rewrite occurrences of declared globals
Description
In order to lower the barrier to adopting `:npm-deps` we could push `:global-exports` a bit further. Instead of just using it to support foreign-libs, we can also use it to automatically make libraries node_modules compatible. This can be done by auto generating a namespace alias if not provided and rewriting global access for matching symbols. Some libs may refer to globals without explicit requires and we should warn in that case.
