Refactor driver cleanup logic into reusable helper function

Extracts duplicate folder removal code across multiple driver modules (Dell, HP, Lenovo, Microsoft) into a centralized `Remove-DriverModelFolder` helper function. This new utility includes safety checks to prevent accidental deletion of the drivers root directory or paths outside the drivers folder hierarchy.

Also moves model path construction in the Microsoft driver module earlier in the function to ensure consistent path handling before any operations that might fail.

Benefits improved maintainability, reduces code duplication, and adds protective safeguards for destructive operations during error handling.
