Generate bindings for IEEE802.15.4 radio on ESP32-C6/H2

[jessebraham]

As previously discussed, we will make esp-ieee802154 depend on esp-wifi-sys so that we can move it into esp-hal and keep that repo blob-free.

I've already confirmed I can build esp-ieee802154 using esp-wifi-sys including these changes.

@bjoernQ do you track changes for esp-wifi-sys in the CHANGELOG here? Happy to add an entry, just want to ask first 😅

I didn't think we need to add a channeling entry for this. Thanks

LGTM - thanks for working on this
