feat(led_indicator): Refactor the components into the Factory Pattern

[zhongchaoesp]

Description

This PR refactors the led_indicator component into a factory pattern, reducing the coupling of API functions.

Original Implementation (Before Refactoring)

Original Configuration Structure:

typedef struct {
    led_indicator_mode_t mode;                  /*!< LED work mode, e.g., GPIO or PWM mode */
    union {
        led_indicator_gpio_config_t *led_indicator_gpio_config;       /*!< LED GPIO configuration */
        led_indicator_ledc_config_t *led_indicator_ledc_config;       /*!< LED LEDC configuration */
        led_indicator_rgb_config_t *led_indicator_rgb_config;         /*!< LED RGB configuration */
        led_indicator_strips_config_t *led_indicator_strips_config;   /*!< LED LEDC RGB strips configuration */
        led_indicator_custom_config_t *led_indicator_custom_config;   /*!< LED custom configuration */
    }; /**< LED configuration */
    blink_step_t const **blink_lists;           /*!< User-defined LED blink lists */
    uint16_t blink_list_num;                    /*!< Number of blink lists */
} led_indicator_config_t;

Original Creation API:

led_indicator_handle_t led_indicator_create(const led_indicator_config_t *config);

Major Changes (After Refactoring)

1. Struct Splitting:

• Generic Configuration (common to all LED types):

  typedef struct {
      blink_step_t const **blink_lists;       /*!< User-defined blink patterns */
      uint16_t blink_list_num;                /*!< Number of blink lists */
  } led_indicator_config_t;

• Device-Specific Configurations (e.g., GPIO LED):

  typedef struct {
     bool is_active_level_high;     /*!< Set true if GPIO level is high when ON */
     int32_t gpio_num;              /*!< GPIO pin number */
  } led_indicator_gpio_config_t;

  (Similar structs created for LEDC, RGB, Strips)

2. API Refactoring:

// Factory functions for different LED types
esp_err_t led_indicator_new_gpio_device(const led_indicator_config_t *led_config, const led_indicator_gpio_config_t *gpio_cfg, led_indicator_handle_t *handle);
esp_err_t led_indicator_new_ledc_device(const led_indicator_config_t *led_config, const led_indicator_ledc_config_t *ledc_cfg, led_indicator_handle_t *handle);
esp_err_t led_indicator_new_rgb_device(const led_indicator_config_t *led_config, const led_indicator_rgb_config_t *rgb_cfg, led_indicator_handle_t *handle);
esp_err_t led_indicator_new_strips_device(const led_indicator_config_t *led_config, const led_indicator_strips_config_t *strips_cfg, led_indicator_handle_t *handle);

Testing

Before:

led_indicator_gpio_config_t led_indicator_gpio_config = {
    .gpio_num = LED_IO_NUM_0,              /**< num of GPIO */
    .is_active_level_high = 1,
};

led_indicator_config_t config = {
    .led_indicator_gpio_config = &led_indicator_gpio_config,
    .mode = LED_GPIO_MODE,
    .blink_lists = led_blink_lst,
    .blink_list_num = BLINK_NUM,
};
led_handle_0 = led_indicator_create(&config);

After:

led_indicator_gpio_config_t led_indicator_gpio_config = {
    .gpio_num = LED_IO_NUM_0,              /**< num of GPIO */
    .is_active_level_high = 1,
};

led_indicator_config_t config = {
    .blink_lists = NULL,
    .blink_list_num = 0,
};

esp_err_t ret = led_indicator_new_gpio_device(&config, &led_indicator_gpio_config, &led_handle_0);

Pull Request Overview

This PR refactors the led_indicator component into a Factory Pattern, introducing per-device creation APIs and removing the legacy mode-based led_indicator_create function.

• Added new factory functions (led_indicator_new_*_device) for GPIO, LEDC, RGB, and Strips.
• Updated all examples, tests, and documentation to use the new APIs and include per-device headers.
• Cleaned up source and header layout, removed legacy files, and conditioned blink defaults on CONFIG_USE_MI_BLINK_DEFAULT.
