[Lib] NeoPixelBus_Wrapper: Allow fall-back to Adafruit_NeoPixel lib for ESP8266

[tonhuisman]

Resolves #4921

Bugfix

Features:

• Make GPIO selection on ESP8266 working again for NeoPixel plugins (except for P128 that never had that option on ESP8266 builds)
• Allow compilation of NeoPixelBus_Wrapper library using Adafruit_NeoPixel library for ESP8266 only
• Add (restore) latest Adafruit_NeoPixel library (+ corrected a few compiler warnings)
• Exclude Adafruit_NeoPixel library from ESP32 builds (not used)
• [P131] Fix compilation warning (-Wreorder)

TODO:

• Testing, help requested:
  • @chemmex ?
  • @fly74 ?

I have only gpio2 wired 8266. I can only test if it still works.

I can only test if it still works.

That's also valuable 👍

First try - onboard LED at GPIO2 is gone, but NeoPixel at GPIO14 is dark. Using P038

Ah, found my mistake (not very experienced C++ programmer here...), will push a fix shortly.

It works!

No issues with a gpio-2 wired 8266 with https://github.com/letscontrolit/ESPEasy/actions/runs/7342236014

Just compiled a new custom build, everything is Ok so far
