Add -n / --no-entry-point flag to nwn_script_comp

[cgtudor]

This flag allows the compilation of a file (or files) without requiring an entry point (void main or StartingConditional). Useful for validating files, the main purpose for its creation is compatibility with the vscode language server which needs to "compile" include files to validate syntax errors even if they don't produce compiled code.

Testing

Manual testing with the following types of .nss scripts:

• Script with a void main()
  • With intentional syntax errors - fails with correct error message
  • Without intentional syntax errors - succeeds
• Script with a StartingConditional
  • With intentional syntax errors - fails with correct error message
  • Without intentional syntax errors - succeeds
• Script without a void main() or StartingConditional
  • With intentional syntax errors - fails with correct error message
  • Without intentional syntax errors - succeeds
