Update Glimmer VM

Updates the VM to the latest version, which includes a number of major
changes:

- Refactors the resolver to not cache values, as this is unnecessary
- Refactors the resolver to return helper/modifier definitions directly
- Refactors the resolver to return ResolvedComponentDefinitions
- Updates various component definitions
- Removes custom helper, modifier, and component managers
- Updates built-in helpers to be based on objects with associated
  helpers/helper managers.
