Replace the macros `LOG_VERBOSE` and `LOG_ERROR` with C++-style streams retrieved through `log_verbose()` and `log_error()`. This aligns with the `MLIR` infrastructure and avoids pollution of the global namespace through a common header file in subsequent refactoring commits splitting the functionality of `src/main.cpp` into multiple files.
