* Ensure that table router is always build

This pr ensures that the table router is always build, aka the future is
resolved. This is important, as the table router internally spawns tasks
to handle gossip messages. Handling gossip messages is not only required
on parachain validators, but also on relay chain validators to receive collations.

Tests are added to ensure that the assumptions hold.

* network/src/legacy/gossip: Wrap GossipEngine in Arc Mutex & lock it on use

`GossipEngine` in itself has no need to be Send and Sync, given that it
does not rely on separately spawned background tasks anymore.
`RegisteredMessageValidator` needs to be `Send` and `Sync` due to the
inherited trait bounds from implementing `GossipService`. In addition
`RegisteredMessageValidator` derives `Clone`. Thereby `GossipEngine`
needs to be wrapped in an `Arc` and `Mutex` to keep the status quo.

* Needed fixes.

* Fixes

* Fixed build

* Fixed build w benchmarking CLI

* Fixed building tests

* Added --dev shortcut
