Add I2S HIL test

[bjoernQ]

ESP32 and ESP32-S2 are not tested since I wasn't able to get it to work there.

However, this test might be really helpful since it's the only test where circular DMA is tested. Also, I2S tends to be hard to test manually

LGTM, thanks!
Regarding ESP32 and S2, it's i2s or hil related issue?

I2S ... I wasn't able to get loopback working there. But since especially a lot of DMA code is shared it's still very helpful for those targets

LGTM! Tried it on H2 and it passes, the only thing is that its a bit slow (~1 min):

      Erasing ✔ [00:00:00] [#] 192.00 KiB/192.00 KiB @ 520.69 KiB/s (eta 0s )
  Programming ✔ [00:00:00] [####] 37.88 KiB/37.88 KiB @ 67.90 KiB/s (eta 0s )    Finished in 0.954s

Awesome .... the frequency on H2 is apparently so slow it takes forever to transmit the data. Will disable the test for H2 here and open an issue

Feel free to add it here #1524 if you prefer

Thanks!

For H2 see: #1637

Sorry, let's just disable that interrupt test. I have no idea was is introducing the variability in the latency.
