feat(button): Refactor button press enum values and add BUTTON_PRESS_…

…NORMAL event

- Refactored the enum values for button press in `iot_button.h` to include a new value `BUTTON_PRESS_NORMAL`.
- Added calls to the event callback function for `BUTTON_PRESS_NORMAL` in `iot_button.c` when the button is pressed down or released.

These changes improve the clarity and flexibility of handling different button press events.
