[rocprof-sys] Refactor trace_cache architecture with improved type erasure and processing pipeline (#1710)

- Redesigned buffer_storage with a flush_worker pattern for better thread management and resource cleanup
- Introduced type-safe abstractions through new components: cacheable.hpp, cache_type_traits.hpp, sample_processor.hpp, and type_registry.hpp
- Optimized type erasure implementation in sample processor to reduce runtime overhead
- Renamed rocpd_post_processing to rocpd_processor and restructured the processing pipeline
- Removed storage_parser.cpp and integrated functionality into header-based template implementation
- Enhanced cache_manager with improved processing workflow and better separation of concerns
