Async WiFi

[MabezDev]

This PR adds embassy_net support to esp-wifi, along with a embassy based DHCP example. Currently connecting to WiFi is blocking, and is completed before starting the executor. This is mainly due to the embedded_svc traits for wifi being blocking at the moment, but we could easily add our own async interface to WiFiDevice in another PR.

TODO

• Use 'upstream' version of bleps once Bump embedded-io bjoernQ/bleps#4 is merged

Awesome! ❤️

I also don't see any problems from using embedded-io 0.4.0 in bleps - no idea if I hallucinated that before 🤷‍♂️ will merge that

but there is a crash now with the ESP32-S3 BLE example

but there is a crash now with the ESP32-S3 BLE example

Looks like we're running into the loop optimization issue again, "-C", "target-feature=-loop", with a git version of xtensa-lx-rt and it works in release (also works in debug btw). We should cut a release of xtensa-lx-rt and default to disabling loop optimization for now I think.

Ah yes - I once again forgot about that - I agree and it shouldn't hold us back from getting this in
