[Core] Better debugging at entities_utilities in debug mode

[loumalouomega]

📝 Description

This commit affects the kratos/utilities/entities_utilities.cpp file. Changes were made in various parts of the file:

1. Licenses were adjusted in lines 7 and 8 to adhere to the proper format and alignment.
2. Verification was added in the GetPrototypeEntity functions to ensure that the prototype is initialized before accessing it, generating error messages if not. This is done for both a GeometryType pointer and a GeometryType reference. (Only in debug)
3. A specific error message was added that displays the type of geometry that lacks an initialized prototype in case the verification fails. (Only in debug)

This will improve debugging processes

🆕 Changelog
