Refactor MSI extraction for improved reliability

Browse Source 
Implements a dedicated mutex to serialize MSI extraction operations. This prevents race conditions when multiple driver packages are processed in parallel by different tasks.

Adds a post-extraction verification step to ensure the target directory is not empty. This guards against silent failures where `msiexec` exits successfully but extracts no files, triggering a retry if necessary.
