Implement "Log System Fee" ACTION

[DenisCarriere]

Purpose

Create logsystemfee ACTION to be used for logging system fees (RAM, Name Bids, Powerup CPU & NET).

Analytics platforms can use this action to track system fees and provide insights to users.

Currently the only way to calculate fees is to parse each action and calculate the fees based on the action type.
