Refactor smart contract service's handling of gas and fees

[lukelee-sl]

Problem

Currently, the code path for handling gas charges in exception scenarios is complex and difficult to maintain. Refactor and simplify.

Solution

• [x] Look into removing AbortException and always charge gas as mono service fidelity is no longer required.
• HandleException has a parameter called shouldRollbackStack which is processed by DispatchProcessor when handling ContractCall exceptions. Analyze and simplify
