Update CMake configuration and .clangd settings for improved build management

- Removed unnecessary compile flags from .clangd to streamline configuration.
- Added YAZE_BUILD_LIB option in CMakeLists.txt for conditional library building in minimal builds.
- Enhanced SDL2 CMake configuration to set include directories for bundled SDL, ensuring proper integration.
- Updated test CMakeLists.txt to conditionally link yaze_c and ImGuiTestEngine based on build options, improving modularity and flexibility.
- Refactored test_editor.cc and test_editor.h to conditionally include ImGuiTestEngine headers and manage engine initialization based on availability.
