Stable esp-radio tracking issue

[MabezDev]

This is a tracking issue for the min stabilization of esp-wifi. The minimal stabilization is defined as:

• Stable esp-wifi::init, with some non_exhaustive config.
• Stable access to an STA interface
• STA interface (feature gated) impls for both embassy-net-driver and smoltcp-driver
• Minimal controls for WiFi, connect, scan etc.

To get here will require a few steps, of which will be outline in this tracking issue.

I hope this is the right issue for this, but I was thinking about how to handle PHY initialization in a way, that's usable outside esp-radio, since I would like to use that in esp-wifi-hal as well.

Is esp-alloc also getting stabilized along with this?
