ApiVisualEditor constructs on EditPage to be able to retrieve the formatted "templates on this page" list.
It should be possible to get the formatted list without using an EditPage object

While a new system is being created for retrieving the formatted list, TemplatesOnThisPageFormatter should have a factory rather than callers needing to independently provide a LinkRenderer, and the PermissionManager that is used should be injected rather than retrieved from MediaWikiServices::getInstance()

Plan:

• Add a TemplatesOnThisPageFormatterFactory to create TemplatesOnThisPageFormatter objects
• Add a method to the Formatter to get the list wrapped in a div with the templatesUsed class, as currently provided by EditPage::makeTemplatesOnThisPageList
• Add a PermissionManager as an optional dependency, hard deprecate not providing it (callers should not construct the class directly, but should use the factory)
• Replace the use of the EditPage object in ApiVisualEditor that relies on makeTemplatesOnThisPageList (use the new factory instead)
• Deprecate EditPage::makeTemplatesOnThisPageList
