[FEATURE] Make Duckdb a core dependency, remove QPD

[goodwanghan]

QPD was created when there was no good local SQL solution. Duckdb is now very mature and very lightweight. So it's time to totally remove QPD from the core dependency and use DuckDB instead.

Also DuckExecutionEngine should become NativeExecutionEngine. We need to merge these two.

Is it possible that QPD is not maintained anymore? The link pointing to the repository from https://pypi.org/project/qpd/ is broken...

I am having a dependency conflict in my project that traces back to QPD (which requires antlr4-python3-runtime<4.12 >=4.11.1, while other dependencies I need depend on antlr4-python3-runtime==4.9.*), so it would help me very much if fugue dropped the dependency on QPD...
