Revisit HIL

[SergioGasquez]

Revisit HIL CI and see how we can improve it. I would like it to cover more corner cases and more arguments. Maybe we need to add some xtask integration to make things easier?

Shall we also cover cargo-espflash with some ESP-IDF application?

We could also add a checksum-md5 test

There are also some known issues (Already fixed):

• flash test needs to use --no-skip otherwise it won't flash anything:
