Add integration tests for Dungeon Editor and object parsing functionality

Browse Source 
- Updated CMakeLists.txt to include new test files for CPU, PPU, SPC700, APU, and dungeon editor integration tests.
- Introduced new testing helpers in testing.h for validating StatusOr objects with specific error messages and codes.
- Added comprehensive integration tests for the DungeonEditor, covering object parsing, rendering, and room graphics.
- Created mock ROM and object data setups to facilitate testing without real ROM files.
- Implemented various test cases to ensure the reliability of object parsing and rendering logic in the dungeon editor.
