Refactors testbench build and execution logic

Updates `build_testbench` to use a shared tool execution utility, improving maintainability and consistency.
Refactors `run_testbench` to accept project configurations, enabling better customization and handling of tool options.

Enhances modularity and reduces redundancy in the simulation workflow.
