A new approach for erasing WiFi Settings (#8828)

Browse Source 
* A new approach for erasing WiFi Settings

Add support for hardware reset function call - simulates EXT_RST via HWDT.

Add reset selection to `ESP.eraseConfig()` for calling hardware reset
after erasing the WiFi Settings.

Update ArduinoOTA to use `ESP.eraseConfig(true)`

Externalized `ArduinoOTA.eraseConfigAndReset()`

Add OTA examples to illustrate using erase config changes.

* style
fixed confused example

* improve wording

* Add new state to retry eraseConfigAndReset

* Removed unreachable error test from examples.

Removed continuous retry of "eraseConfig" and allow the script to
assign an error handling option for "eraseConfig" failure.

Update example to use error handling option.

* In eboot for function ets_wdt_enable() added missing arguments

* Update comments and example

* Wording

* Rebuilt eboot.elf with current tools from ./get.py

* Requested changes.

* cleanup comments

* Update hardware_reset

Avoid using "[[noreturn]]" - not accepted for a .c file function
Updated to use __attribute__((noreturn)) to handle both .cpp and .c
file functions.
