Description

Closes #2566

We have the qa-test folder but running those tests was annoying and error-prone.

While it was always possible to run cargo xtask run-example FOLDER TARGET (i.e. w/o the example name) it always gave an error.

Now it will

• run all examples / tests for the given chip
• show the top-level comment - give the user time to attach / prepare whatever is needed
• let the user decide to run or skip the example (e.g. if the user doesn't have the needed external components at hand)
• run next example when the example was quit via CTRL-C

Additionally, this introduces a new key TAG which is used to group the examples (i.e. multiple examples needing the same wiring should run after each other)

In future we will move everything from examples over to qa-test (and adapt those examples to better serve as tests) but that is out of scope for this PR.

skip-changelog since this isn't really worth mentioning there

LGTM, thanks! Also did some testing and now its way more convenient to test all the qa tests! Maybe we should thing if we require any other tag(s), maybe a tag for those qa-tests that dont require any extra-stuff is helpful
