Similar to how MWNamespace was replaced with a NamespaceInfo service, I propose that MWGrants be replaced with a GrantsInfo service.

The different static MWGrants methods use:

• The LanguageFactory service
• The LinkRenderer service
• The ContentLanguage service (which is just the LanguageFactory with the LanguageCode config value)
• wgGrantPermissions
• wgGrantPermissionGroups

The services can be injected to the new GrantsInfo class, as well as a ServiceOptions object with the needed configuration values
