Add VSCode native debug launcher that attaches to java process.

In my experience on linux searching for "executor" brings up  the "Gradle Test Executor" java process of interest when debugging tests hanging in native code.

Note that the sourceFileMap assumes that that wpilib source is installed under $HOME/git/allwpilib. If it isn't, you can still see stack traces, you just won't be able to see the wpilib source.

The "program" location probably needs a windows specific version, maybe with ${env:HOME} replaced with ${env:ALLUSERSPROFILE}?
