Enable dynamic governance model for transaction gas base fee

[DogeProtocol]

Rationale

Currently, the base fee for gas is hardcoded.

Why should this feature exist?
What are the use-cases?

A governance model can better help build the platform by allowing gas fee to be voted. The gas fee can be dynamically determined by allowing anyone to specify a smart contract that returns the gas fee and PoS stakes to vote and accept or reject this smart contract.
