This commit creates two concrete classes Inline and External TemplateSource to differentiate between templates in TS file and HTML file. Knowing the template type makes the code much more explicit which filetype we are dealing with. With these two classes, there is no need for `getTemplateAt()` method in TypeScriptHost. Removing this method is safe since it is not used in the extension. This reduces the API surface of TypescriptHost. PR Close #32127
