Pull latest pigweed version. (#20158)

* Pull latest pigweed version.

```
cd third_party/pigweed/repo
git fetch https://github.com/google/pigweed.git main
git checkout FETCH_HEAD
```

* change std::span/std::as_bytes to pw::span/pw::as_bytes to make pigweed polyfill happy

* Switch include: from span to pw_span.h

* More replacing of std::span with pw::span

* Restyle

* Set pw_span_ENABLE_STD_SPAN_POLYFILL to false for anything that sets a sys_io_BACKEND

* fix amebad-pigweed builds

* Ensure import is done for polyfill settings for Amebad

* Fix ESP32 builds with pw_span

* Restyle
