Enable changing executor params through governance (#6934)

Browse Source 
* Add a pallet call to change executor params

* Use `OptionQuery`; Avoid runtime panic

* Move pending executor params to `configuration`

* Move `ExecutorParams` to `HostConfiguration` structure

* Add executor params to the v5 migration

* Add an `ExecutorParams` benchmark

* ".git/.scripts/commands/bench/bench.sh" runtime polkadot runtime_parachains::configuration

* Add to `WeightInfo`

* Add dummy weights to other networks

* ".git/.scripts/commands/bench/bench.sh" runtime kusama runtime_parachains::configuration

* ".git/.scripts/commands/bench/bench.sh" runtime rococo runtime_parachains::configuration

* ".git/.scripts/commands/bench/bench.sh" runtime westend runtime_parachains::configuration

* Use real weight

* Fix comment
