REFACTOR: Improve API and security in Desktop

[SMoraisAnsys]

Description

The PR consist in a refactoring of the desktop module to clean it and strengthen the calls related to subprocess. On top of that, a new section has been added to the documentation to notify about the risk of using insecure commands.
Changes are:

• use __ method instead of _ method when it makes sense;
• move inner methods to other modules when possible;
• use @min_aedt_version("2023.2") on simulation related property / methods;
• reorder private / public / property into subsets;
• add documentation on security considerations;
• strengthen methods related to subprocess to avoid launching abitrary executable on the system.
