Make the maximum block size configurable (#7499)

Browse Source 
* Make the maximum block size configurable

This pr makes the maximum block size configurable. The maximum block
size is used after proposing a new block to check if the new block is
not exceeding the maximum.

* Update primitives/consensus/common/src/evaluation.rs
