Refactor EditorManager and Tile16Editor for improved functionality and error handling

- Commented out the ArenaTestSuite registration in EditorManager with a TODO for future implementation.
- Updated the DrawMenuBar method in EditorManager to enhance version display alignment and tooltip functionality.
- Modified OverworldEditor to include error handling for ASM application and commented out the Asar wrapper for build compatibility.
- Enhanced Tile16Editor with additional bounds checks and error handling to ensure robustness during tile operations.
- Introduced new test cases in RomDependentTestSuite for Tile16Editor functionality and comprehensive save operations, improving test coverage.
