Adds check_inherents function to the BlockerBuilder API (#912)

Browse Source 
* Adds new `check_inherents` function to the `BlockBuilder` API

* Switch to `check_inherents` in `node-consensus`

* Remove `CheckedBlock`, because it is not required anymore

* Fixes after rebase

* Fixes compilation on stable
