use account changes as int

[BeniaminDrasovean]

Reasoning behind the pull request

• Simplification of the stateAccess struct

Proposed changes

• Instead of using a new struct that contains only boolean values for accountChanges, encode the changes using an uint32

Testing procedure

• Tested in feature branch

Pre-requisites

Based on the Contributing Guidelines the PR author and the reviewers must check the following requirements are met:

• was the PR targeted to the correct branch?
• if this is a larger feature that probably needs more than one PR, is there a feat branch created?
• if this is a feat branch merging, do all satellite projects have a proper tag inside go.mod?

Pull Request Overview

This PR changes the representation of account changes from a struct with boolean fields to a uint32 bitmask representation to improve performance and memory usage.

• Changes GetAccountChanges method signatures to return uint32 instead of *stateChange.AccountChanges
• Updates account change detection logic to use bitwise operations instead of struct field assignments
• Modifies tests to use new bitmask constants and operations
