feat: Defer cleanup of compressed driver source folders

Browse Source 
Implements a deferred cleanup mechanism for driver source folders when they are compressed to a WIM and also used for WinPE.

When drivers are compressed, the original source folders are now preserved if they are also needed for WinPE driver injection. A marker file is created in these preserved folders.

A new cleanup step is added after the WinPE media creation to remove these preserved folders, ensuring they are available when needed but not left behind permanently.
