liveview: Add `interpreter_glue_relative_uri (#1481)

* liveview: Add `interpreter_glue_relative_uri`

By utilizing `window.location.host` in the client-side JavaScript, we can easily derive the WebSocket URI from a relative path URI. This approach obviates the need for host address retrieval on the server side, unlike the method of serving glue code in liveview using `interpreter_glue`.

* liveview: Merge `.._relative_url` functionality

- Merged `.._relative_url` to current API `interpreter_glue`.
- Edit axum example to work with new feature.

* liveview: Fix clippy warning
