QtGP Add Types for QtGP Test classes

Why?

Cause

• To get rid of unnecessary warnings in tests.
  • There are many places where we are using an extension or build task and it shows a yellow highlight or a gray method name even though it exists.
• To make the code more easily readable, thanks to better Groovy syntax highlighting.
