refactor: simplify bind_one logic and consolidate pci write handlers

[bhagathkrishnacdac]

Description
This PR refactors the PCI device binding function (bind_one) in the DPDK binding utility to simplify exception handling and guarantee file resource safety.

Key Changes

• Context Managers (with): Replaced manual, unsafe open() and close() operations with Python context managers to guarantee file closure during I/O failures.
• Consolidated File Handlers:
  • Extracted _prepare_pci_driver to manage driver_override and new_id updates for kernel compatibility.
  • Extracted _finalize_bind to handle standard binds and automate driver rollback operations on failure.
• Unified Exception Catching: Grouped separate file-open and file-write try/except segments into unified blocks catching (OSError, IOError) exceptions, reducing function length and complexity.
