[ECU STM32] Implement Status LEDs Driver

[AksonovSergei]

📌 Requirements

1. The component should control all status LEDs (lights) connected to the board.
2. The component should have two parts:

• Driver: This is the code that makes the LEDs light up in different ways.
• Manager: This is the code that connects the driver to the project. It reads settings from a database and tells the driver what to do based on those settings.

3. The driver must provide an API for initialization.
4. The number of LEDs can change and will be set when the code is built (at compilation time).
5. The driver should provide a simple way to set up how each LED connects to the board's pins (GPIO).
6. The driver must provide an API to turn an LED on.
7. The driver must provide an API to turn an LED off.
8. The driver should provide an API to make an LED blink 'n' times. If 'n' is 0, the LED should blink forever. Blinking means the LED is on for 50% of the time and off for 50% of the time (50% duty cycle).
9. The driver should provide an API to make an LED flash 'n' times. If 'n' is 0, the LED should flash forever. Flashing means the LED is on for 10% of the time and off for 90% of the time (10% duty cycle).
