app/javascript/mastodon/main.js delayed the execution of modules,
but other entry points didn't. That leads to failure in executing
modules, which requires those polyfills.

Strictly enforce the rule to require any modules after loading
polyfill in entry points.

JavaScript error at Safari 10.1(macOS 10.12.4) / iPhone Safari(iOS 10.3.2)

* Create common chunk rather than vendor chunk

vendor chunk is a set of modules provided by external vendors, but now we
can have a chunk as a set of modules shared by multiple entry points,
which could be more efficent than having vendor chunk.
