Kt/Native Adding interop to build process improvements

[AlexPl292]

1. Additional parameters section should be removed because it's not necessary to finish this tutorial, but this large code block takes a lot of attention.
2. Once done, you can now build the project and access the headers from Kotlin as we'll see in the next step. - anything should be done to attract more attention to this line. This line is very important, but 1) it's placed at the end of page 2) It's partially overlapped by back button 3) It's placed after unnecessary section (see above).
