Refactor test structure and enhance object encoding tests

- Updated CMakeLists.txt to correct file paths for unit tests.
- Modified DungeonObjectRenderingE2ETests to inherit from BoundRomTest for better ROM management.
- Enhanced DungeonEditorIntegrationTest with improved mock ROM handling and added graphics data setup.
- Introduced a new MockRom class with methods for setting mock data and initializing memory layout.
- Added comprehensive unit tests for RoomObject encoding and decoding, covering all object types and edge cases.
- Refactored DungeonObjectRenderingTests to utilize BoundRomTest, ensuring consistent ROM loading and setup.
- Improved assertions in rendering tests for better clarity and reliability.
