Rename isInternal parameter to noValidation

[Arlodotexe]

Renames the isInternal parameter to noValidation in constructors of SystemFile and SystemFolder classes, and updates related comments to reflect this change.

• Parameter Renaming:
  • Renames the isInternal parameter to noValidation in the internal constructors of both SystemFile and SystemFolder classes. This change is applied to differentiate between public and internal constructor usage more clearly.
• Comment Updates:
  • Updates the code comments above the internal constructors in both classes to accurately describe the purpose and usage of the noValidation parameter, ensuring that the documentation remains consistent with the code.
