The `LinkInterceptor` class contains some Frame-specific checks that were at the root of `<a data-turbo-method="...">` element clicks submitting multiple HTTP requests. To resolve the underlying issue, this commit changes the `FormLinkInterceptor` class to rely on an instance of `LinkClickObserver` instead of `LinkInterceptor`. In order to make that possible, this commit also extends the `LinkClickObserver` to accept a second argument to server as the [EventTarget][] for the `click` event listeners. As a consumer, the `FormLinkInterceptor` instances attached to `<turbo-frame>` element scope their listeners to the element, while the `Session`'s `FormLinkInterceptor` instance attaches a catch-all listener to the `window`. Since this commit changes the underlying event listening mechanism, it also renames the `FormLinkInterceptor` and delegate to `FormLinkClickObserver` to match the `LinkClickObserver` naming patterns.
