support embassy-net with simplified lifetimes/generics

[jsprog]

Motivations

embassy-net simplified lifetimes/generics since be0d977 (Sep 16, 2024). Sooner or later, esp-hal need to catch up. After updating embassy-net, I'm unable to create Stack<'d> instances due to a missing trait bound Driver.

the trait bound `WifiDevice<'_, WifiStaDevice>: Driver` is not satisfied`.

Additional context

I already spotted some changes

• struct Stack<D: Driver> is now Stack<'d>
• embassy_net::new(params) instead of embassy_net::Stack::new(params)
• embassy_net::new(params) returns with a tuple (Stack, Runner). Stack is for creation of Sockets (note: they are Copy) and Runner is for the background work.

esp-wifi will be updated once a new embassy-net version has been released. If you'd like to prepare an interim PR that brings our API closer, and maintain that PR until a release is made, we'd be grateful.
