Implement a forked sort package from go1.13 for stable masternode sorting

[endale98]

Description

This PR addresses the issue of ensuring stable sorting of masternodes across different Go versions. To achieve this, we have forked the sort package from Go 1.13 and implemented it specifically for the masternode sorting algorithm.

The forked sort package guarantees consistent behavior, providing stability and reliability in the sorting process regardless of the underlying Go version.

Changes

Utility Functions:

• common/sort/slice.go.
• common/sort/sort.go.
• common/sort/slice_go113.go.
• common/sort/genzfunc.go.
• common/sort/zfuncversion.go.

Import Changes:

• core/blockchain.go: Updated import statement to use the new sort package from github.com/tomochain/tomochain/common/sort.

Tests:

• common/sort/example_interface_test.go.
• common/sort/example_keys_test.go.
• common/sort/example_multi_test.go.
• common/sort/example_test.go.
• common/sort/example_wrapper_test.go.
• common/sort/export_test.go.
• common/sort/sort_test.go.

Impact

This change ensures:

• Consistent sorting behavior across Go versions.
• Stable and predictable masternode operations, improving reliability of the system.
