Refactor GaugeBucketCollector metrics to be homeserver-scoped (#18715) 
Refactor `GaugeBucketCollector` metrics to be homeserver-scoped

Part of https://github.com/element-hq/synapse/issues/18592


### Testing strategy

 1. Add the `metrics` listener in your `homeserver.yaml`
    ```yaml
    listeners:
      # This is just showing how to configure metrics either way
      #
      # `http` `metrics` resource
      - port: 9322
        type: http
        bind_addresses: ['127.0.0.1']
        resources:
          - names: [metrics]
            compress: false
      # `metrics` listener
      - port: 9323
        type: metrics
        bind_addresses: ['127.0.0.1']
    ```
1. Start the homeserver: `poetry run synapse_homeserver --config-path
homeserver.yaml`
1. Fetch `http://localhost:9322/_synapse/metrics` and/or
`http://localhost:9323/metrics`
1. Adjust the number of [`msecs` in the `looping_call` so that
`_read_forward_extremities`](a82b8a966a/synapse/storage/databases/main/metrics.py (L79))
runs immediately instead of after an hour.
1. Observe response includes the `synapse_forward_extremities` and
`synapse_excess_extremity_events` metrics with the `server_name` label
