Benchmark hierarchical consensus processes (SCA, block validation, events, etc.)

[adlrocha]

We may have introduced additional delays in the critical path of block validation and message execution by integrating hierarchical consensus. We should benchmark functions in the SCA, the execution of messages and cross-messages, and block validation to understand where we may have introduced overheads, and to try and fix it or come up with alternatives.

This may be an issue for the integration of hierarchical consensus in Filecoin as (apparently) it affect the block validation times of Filecoin consensus miners.
