Instead of spreading the enum information all around the codebase
between different modules like models and GraphQL types, we can set a
single source of the truth for the Enum values.

To do so, we should promote the enums to be first class members of the
project by giving them a new top level directory to live in.

Add `gl-button` to move issue button in issue sidebar

See merge request gitlab-org/gitlab!51285

- It is important that we update the route to the new
  branch.
- Also, we add a "destroy" event to the root component
  so that the spec can properly dispose of Singleton
  things. Otherwise, specs were bumping into eachother
  because Monaco models were being shared.

This actually caused a number of issues and
left the Web IDE in a broken state.
