chore(cmake): enhance CMake configuration for Abseil and yaml-cpp

- Made ABSL_TARGETS available to the rest of the project via include(), improving modularity.
- Added MSVC-specific compile options for yaml-cpp to address exception handling warnings.

Benefits:
- Streamlined integration of Abseil targets across the project.
- Improved compatibility and reduced warnings for yaml-cpp on MSVC.
