Don't rely on QuickInputService in EditorResolverService

I'm trying to allow validation messages in the quick pick to support links. Unfortunately, adding OpenerService to the QuickInputService has left me in a service dependency cycle: - IQuickInputService - [IOpenerService](https://github.com/microsoft/vscode/blob/613bac1aa4a8ccd6a11df50158858821ee3d064f/src/vs/editor/browser/services/openerService.ts#L99) - [ICodeEditorService](https://github.com/microsoft/vscode/blob/613bac1aa4a8ccd6a11df50158858821ee3d064f/src/vs/workbench/services/editor/browser/codeEditorService.ts#L19) - [IEditorService](https://github.com/microsoft/vscode/blob/613bac1aa4a8ccd6a11df50158858821ee3d064f/src/vs/workbench/services/editor/browser/editorService.ts#L37) - [IEditorResolverService](https://github.com/microsoft/vscode/blob/613bac1aa4a8ccd6a11df50158858821ee3d064f/src/vs/workbench/services/editor/browser/editorResolverService.ts#L41) - IQuickInputService Can we move things around so the resolver service doesn't depend on QuickInput? Logan had the idea of moving the usage into the commands which makes sense to me.
