RFR: 8269761: idea.sh missing .exe suffix when invoking javac on WSL [v4]

[Jorn Vernee]

> From the JBS issue:
> 
> At the end, idea.sh tries to invoke javac, but when running on WSL this results in the following error:
> 
>     bin/idea.sh: line 249: /mnt/c/progra~1/java/jdk-16/bin/javac: No such file or directory
> 
> Adding a .exe suffix to the javac path fixes this issue, which can be done just for WSL.
