Change ToolOutput to ToolView (#11682)

Additionally, the internal `ToolView` trait used by the registry is now
called `InternalToolView`.

This should make it a bit easier to understand that the `ToolView` is
intended for a `gpui::View` (implementing `Render`). It does still feel
like more could be merged here but I think the built tools are now a bit
clearer.

Release Notes:
