Add typed hook system for plugins

Replace invokeHook and the per plugin on* methods with AsyncHook
collections on the controller, host, instance, clusterioctl and web
control objects. Plugin entrypoints export a default function that
receives a load context and attaches handlers to the hooks it needs.
Class exports still load through fromContext with a deprecation
warning. The create templates and docs use the entrypoint function.

This is clusterio/clusterio#921 recreated on top of master after the
ESM migration and the PluginDeclaration permissions change.

Closes #730
