[BUG NOTE]Marlin 2.1.2.2/ bugfix 2.1.x is broken for ESP3DLib 1.0

[luc-github]

MarlinFirmware/Marlin@fecadac removed all configurations flags access for ESP3DLib

In Configuration_adv.h

Latest changes prevent ESP3D_WIFISUPPORT to use :

#define WEBSUPPORT          // Start a webserver (which may include auto-discovery) using SPIFFS
#define OTASUPPORT          // Support over-the-air firmware updates
#define WIFI_CUSTOM_COMMAND // Accept feature config commands (e.g., WiFi ESP3D) from the host

You need to replace/put back:
#if ENABLED(WIFISUPPORT) by #if ANY(WIFISUPPORT, ESP3D_WIFISUPPORT)

Or add the flags outside of the #if ENABLED(WIFISUPPORT)

If not, ESP3DLib cannot communicate with Marlin and is not setup for web access

In SanityCheck.h

change

/**
 * Sanity check WiFi options
 */
#if ALL(WIFISUPPORT, ESP3D_WIFISUPPORT)
  #error "Enable only one of WIFISUPPORT or ESP3D_WIFISUPPORT."
#elif ENABLED(ESP3D_WIFISUPPORT) && DISABLED(ARDUINO_ARCH_ESP32)
  #error "ESP3D_WIFISUPPORT requires an ESP32 motherboard."
#elif ALL(ARDUINO_ARCH_ESP32, WIFISUPPORT)
  #if !(defined(WIFI_SSID) && defined(WIFI_PWD))
    #error "ESP32 motherboard with WIFISUPPORT requires WIFI_SSID and WIFI_PWD."
  #endif
#elif ENABLED(WIFI_CUSTOM_COMMAND)
  #error "WIFI_CUSTOM_COMMAND requires an ESP32 motherboard and WIFISUPPORT."
#elif ENABLED(OTASUPPORT)
  #error "OTASUPPORT requires an ESP32 motherboard and WIFISUPPORT."
#elif defined(WIFI_SSID) || defined(WIFI_PWD)
  #error "WIFI_SSID and WIFI_PWD only apply to ESP32 motherboard with WIFISUPPORT."
#endif

Hi Luc! Sorry about that.

2.1.2.2 may not get retagged with fixes, but hopefully my PR (MarlinFirmware/Marlin#26822) will get merged into bugfix-2.1.x soon and it'll restore ESP3D support.
