fix(pins_arduino): Fixes te mask for the Watchy Device pins

[SuGlider]

Description of Change

Based on user report, the Watchy pins-arduino.h causes compilation error.
It shall follow https://github.com/sqfmi/Watchy/blob/master/src/config.h

Test Scenarios

Select Watchy board and try to compile a basic sketch
The board revision will default to "Watchy 2.0". Leave it that way.

Open Arduino IDE Examples -> Watchy -> WatchFaces -> Basic.ino

#include <Watchy.h>
#include "settings.h"

Watchy watchy(settings);

void setup() {
  watchy.init();
}

void loop() {}

Error Message that shall be fixed with this PR:

Pull Request Overview

This PR fixes compilation errors in the Watchy device pins configuration by replacing deprecated GPIO_SEL_* constants with BIT64() macro calls. The issue was causing builds to fail when using the Watchy board with Arduino IDE examples.

• Replaces hardcoded GPIO_SEL_* constants with dynamic BIT64() macro calculations
• Removes version-specific UP_BTN_MASK definitions and consolidates mask definitions
• Updates all button and interrupt pin masks to use the corrected format
