BREAKING CHANGE: Avoid collisions between static class/namespace members
This commit changes the delimiter between namespaces and their members from "." to "::" in internal names. The new delimiter certainly feels very un-JavaScript-y, but the meaning is still recognizable, and these names aren't exposed to users in most cases anyway. Still, this is a breaking change, as it affects the import names for `declare namespace` members (as seen in tests/compiler/declare.js), and transform authors will also need to update their code accordingly. Fixes AssemblyScript#2793.
