Fix https://github.com/element-hq/synapse/issues/18735 In https://github.com/element-hq/synapse/pull/18670, we updated `run_as_background_process` to add a `server_name` argument. Because this function is directly exported from the Synapse module API, this is a breaking change to any downstream Synapse modules that use `run_as_background_process`. This PR shims and deprecates the existing `run_as_background_process(...)` for modules by providing a stub `server_name` value and introduces a new `ModuleApi.run_as_background_process(...)` that covers the `server_name` logic automagically.
