[SuGlider]

Description of Change

Adds a const uint8_t BOOT_PIN for each ESP32 SoC that can be used in the Arduino Sketch.

Tests scenarios

CI and testing sketch:

void setup() {
  pinMode(BOOT_PIN, INPUT_PULLUP);
  Serial.begin(115200);
}

void loop() {
  if (digitalRead(BOOT_PIN) == LOW) {
    Serial.println("Boot Button is pressed.");
  } else {
    Serial.println("Boot Button is released.");
  }
  delay(3000);
}
