## Motivation
- Structured logging with proper log levels (TRACE, DEBUG, INFO, WARNING, ERROR, CRITICAL)
- Better performance through compile-time formatting
- Consistent formatting using fmt library
- Runtime log level control via arguments and environment variables
- Easier maintenance and debugging capabilities
## Technical Details
- Added spdlog as a submodule and integrated it into CMake build system
- Created new `rocprofiler-systems-logger` library wrapping spdlog functionality
- Replaced custom logging macros (`ROCPROFSYS_VERBOSE`, `ROCPROFSYS_DEBUG`, `ROCPROFSYS_FATAL`, `ROCPROFSYS_REQUIRE`, `ROCPROFSYS_CI_THROW`, etc.) with spdlog equivalents (`LOG_DEBUG`, `LOG_WARNING`, `LOG_CRITICAL`, etc.)
- Implemented log level control through command-line arguments and environment variables
- Converted assertion macros to proper error handling with exceptions and std::abort()
* refactor: centralize update_env across binaries with unit test added for testing
* removed unused includes suggested by clangd and small cleanup
* use centralized update_env in argparse as well
* review comments incorporated
* move update_env tests closer to common library
* fix: missing common:: prefix in rocprof-sys-sample
* cmake formatting
