Test : Godot full AST reconstruction and compile validation

Note: This validation test has not been implemented yet.

Repo : https://github.com/godotengine/godot

• Download the Unreal source code
• Find paths of every header and source file
• Generate an ast for each file and serialize it to a file called <name of file>.gen.<h/c>
• Reconstruct the ast from the generated file
• Compare the original ast to the reconstructed ast
• If all ASTs are considered valid, overwrite the original files with the generated files
• Compile the engine.

Currently the most involved test planned for the library.
