Charge transaction for fields that slow down block production

Blocked

This issue is better to do after some results in the issues below:

https://github.com/FuelLabs/fuel-core/issues/1387 https://github.com/FuelLabs/fuel-core/issues/1402

However it is still possible to do an analytic analysis of the code and guess on potential issues.

Overview

While some fields slow down transaction verification, other fields may slow down the block production. Maybe inserting giant witnesses into the database is slow, or sharing massive blocks/transactions slowdown the TPS of the network, or moving massive objects in memory is a slow operation, etc.

Solution

Start to charge users for fields that slow down production time. Mostly, it means including the execution cost into min_fee.

Note

That issue requires some research first or results from linked issues.
