Master5.1 s3 gpio48 and platform txt review

[SuGlider]

Description of Change

This PR follows #8600 and #8562 changes for all necessary variant files / boards.txt.
It also fixes the #8560 issue in the Arduino Core 3.0.0
The PR moves common macros and defines to Arduino.h, not necessary in pins_arduino.h file anymore.
It also adds NEO_LED macros and constants in order to allow using it in a digitalWrite() for Blinking as in the example:

Tests scenarios

Passed boards CI https://github.com/SuGlider/arduino-esp32/actions/runs/6425347486

Testing compilation of a sketch using the new Arduino.h and its changes:

void setup() { int a = NUM_DIGITAL_PINS; int b = NUM_ANALOG_INPUTS; int c = EXTERNAL_NUM_INTERRUPTS; int d = analogInputToDigitalPin(1); int e = digitalPinToInterrupt(2); bool f = digitalPinHasPWM(3); } void loop() { }

Tested the sketch from #8560

// Not a working sketch - Using ESP32-S3 void IRAM_ATTR Callback() { } void setup() { //This does not work: attachInterrupt(digitalPinToInterrupt(48), Callback, FALLING); //This works: attachInterrupt(48, Callback, FALLING); }
