Localize generated debugger package.json strings (#6088)

* Localize debugger package.json strings

This PR updates the generateOptionsSchema to create keys for
package.nls.json that are used in package.json for localization.

This will automatically take the english strings in OptionsSchema.json +
etc and convert them into keys to use for package.nls.json and update
package.nls.json.
