Create utilities for building expression chain AST. visualizations plugin will use those utilities in build_pipeline.ts to construct expression chain AST for each visualization, instead of concatenating strings to construct raw expression pipline string.

• AST builder utilities to construct all parts of expression AST:
  • Chain;
  • Expression function;
  • Arguments;
    • Sub-expressions in arguments;
• Export builder statically for visualization plugin to consume.
