Add HW Runner integration testing CI gate

[tullom]

The large amount of changed files is due to all our examples being retrofitted to run integration tests on them.

I see the need for the yml file and the test folder, double check that you meant to make so many changes in the examples

Feel free to try this on your own machine, simply have your board plugged in, fire up Git Bash, $ cd examples/rt685s-evk/src/bin and run $ ./test.sh. It will build, flash, and run all examples in test mode. The sha256-async test is failing in release mode...
