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 :) cc @espzav
