feat: Enable Unity builds for faster compilation

- Added an option to enable Unity (Jumbo) builds in CMake.
- Updated CMakeLists.txt to conditionally set CMAKE_UNITY_BUILD and batch size.
- Removed outdated analysis documentation for overworld implementation.
- Deleted z3ed resources YAML file as it is no longer needed.
- Refactored CMake files to modularize the build system, separating core, editor, gfx, gui, and zelda3 components into library files.
- Added precompiled headers for various libraries to improve compilation times.
- Updated yaze_config.h.in to define IMGUI_DEFINE_MATH_OPERATORS for C++ compatibility.
- Enhanced editor integration tests with necessary includes for ImGui.
