misc(fuzzer): Enable aggregation fuzzer test with FB-only functions (#…

…12288)

Summary:
Pull Request resolved: #12288

This diff also removes LogicalDummyScan from velox/parse/DuckLogicalOperator.h because this symbol already exists in duckdb/planner/operator/logical_dummy_scan.hpp which causes a linking error due to duplicate symbols
