Cloud feedback Extension (#6626)

This pull request introduces a new extensible system for adding custom
action bar buttons to the top menu, and demonstrates its use by adding a
cloud feedback button. The changes include defining a new
`ActionBarButton` type, updating the extension system to support action
bar buttons, creating a Pinia store to aggregate buttons from
extensions, and updating the UI to render these buttons in the top menu.
The cloud feedback button is now conditionally loaded for cloud
environments.

**Extensible Action Bar Button System**

* Defined a new `ActionBarButton` interface in `comfy.ts` for describing
buttons (icon, label, tooltip, class, click handler) and added an
`actionBarButtons` property to the `ComfyExtension` interface to allow
extensions to contribute buttons.

* Created a Pinia store (`actionBarButtonStore.ts`) that collects all
action bar buttons from registered extensions for use in the UI.

**UI Integration**

* Added a new `ActionBarButtons.vue` component that renders all action
bar buttons using the store, and integrated it into the top menu section
(`TopMenuSection.vue`).

**Cloud Feedback Button Extension**

* Implemented a new extension (`cloudFeedbackTopbarButton.ts`) that
registers a "Feedback" button opening the Zendesk feedback page, and
ensured it loads only in cloud environments.
