Converted all Python 2 scripts to Python 3

[timmattison]

I was unable to compile a few different languages with the compile_all.py scripts. I noticed that some were using the Python 2 style print statements so I converted them all to Python 3 with the 2to3 tool.

I ran:

find . -name "compile_all.py" -exec 2to3 -w {} \;

And then I discarded the following updated scripts that were already converted:

• FSharp/compile_all.py
• Java/compile_all.py
• Java-GraalVM/compile_all.py
• compile_all.py
