Is your feature request related to a problem?

In multi-touch systems, the track ID is a crucial piece of information. Some chips, such as the GT911, inherently support track ID information. We should ensure that the driver exposes this information.

Describe the solution you'd like

like **bool esp_lcd_touch_get_coordinates(esp_lcd_touch_handle_t tp, uint16_t *x, uint16_t *y, uint16_t strength, uint8_t point_num, uint8_t max_point_num)

Describe alternatives you've considered

In GT911's datasheet, it can be supported easily.

@lijunru-hub sounds like a nice feature. We can discuss during next BSP meeting :)
