df: Add DataFrame implementation and tests

Add the core DataFrame implementation with query planning support:
* dataframe.h/cc: Main DataFrame class implementation with public API
* query_plan.h/cc: Query planning infrastructure for DataFrame operations
* dataframe_unittest.cc: Comprehensive test suite for DataFrame functionality

This implementation provides the foundation for efficient data
manipulation and querying in the trace processor, supporting
operations like filtering, sorting, and aggregation.
