remove weight generation for dependent pallets
The original approach was defining weights of dependent pallets inside the runtime: https://github.com/paritytech/substrate/tree/668ecade60abe5a644868aefd3d231c9839fe652/bin/node/runtime/src/weights
Nowadays, this is no longer the case: https://github.com/paritytech/substrate/tree/master/bin/node/runtime/src
We need to remove the few weight definitions from our runtime:
- uniques
- utility
- vesting
And make sure that the weight information is passed where it was forgotten
- session
- scheduler
