Refactors Xilinx ISE tool execution and report handling

Replaces repetitive tool execution logic with a reusable `run_tool` function to streamline code and reduce duplication.

Introduces a shared `copy_report_file` utility for consistent report copying and error handling.

Simplifies individual tool scripts (XST, NGDBuild, MAP, PAR, BitGen) by delegating core logic to common utilities.

Improves maintainability and consistency across the codebase.
