Add VSCode launch configurations (#10683)

* Added debug, attach to debug, test-all, and test-current-file
* The debug and attach to debug allow you to run Appium server
* Made some changes to how package.json is located to support being able to run Mocha tests directly from 'test/' instead of from 'build/test/'
