Pull Request Details 📖

Description

• make esp-wifi::initialize take a PeriodicTimer<ErasedTimer>
• make the embassy time-driver take OneShotTimer<ErasedTimer> references

This enables the user to use any hw-timer for esp-wifi (no matter if from TIMG0, TIMG1 or SYSTIMER) and use any combination of hw-timers for the embassy-time-driver. It also gets rid of the features to select the embassy time-driver implementation.

Testing

Run the (changed) examples ideally at least on ESP32, ESP32-S2 and any other chip

There's a lot to take in here, but overall I think it's looking quite good. Thanks for taking care of this, nice to finally have this implemented!

Side note: The underlying timers probably should wrap modifications on shared registers in a critical-section (#1739 already addresses that for SYSTIMER). That is out of scope for this PR

Sorry for the huge amount of changed code here but I think it makes sense to have this in one PR - fortunately much of the changes are just adapted examples. BTW the examples use different timers and patterns for initialization - that's to show the flexibility of the API and on purpose

LGTM, thanks!
