Port on top of @glimmer/di

[Turbo87]

from emberjs/ember.js#14882:

• Import @glimmer/resolver into ember-resolver.
• Update resolver to inherit from @glimmer/resolver
• For backwards-compatibility, should delegate to old-style resolver rules if something is looked up and not found
• Should also export a resolver with Module Unification-only rules (import Resolver from "ember-resolver/turbo"?)
• Release new version on npm

@tomdale @rwjblue how is "Import @glimmer/resolver into ember-resolver" meant? should we add it as an NPM dependency and use e.g. broccoli-rollup to import it into the build?

@Turbo87 I believe https://github.com/201-created/dangerously-set-unified-resolver/tree/glimmer-resolver is the latest of this. In #180 I've added feature flags to the resolver. This will make it possible to only include glimmer/di for applications that opt-in to that mode.

This is implemented in 4.1.0 via #182. Let me know if I've missed something!
