shields: rpi_pico_lcd: add PiMoroni Pico LCD 2

The new part of the Raspberry Pi Pico LCD shield by PiMoroni is:

  * PIM580 Pico Display Pack 2.0, here in Bridle known as
    PiMoroni Pico LCD 2 (pimoroni_pico_lcd_2)

supported features:

  * display API (zephyr/samples/drivers/display)
  * LVGL stack (zephyr/samples/subsys/display/lvgl)
  * input API (zephyr/samples/subsys/input/input_dump)

supported platforms:

  * Raspberry Pi Pico (rpi_pico)
  * Raspberry Pi Pico W (rpi_pico_w)
  * Waveshare RP2040 Plus 4MB (waveshare_rp2040_plus)
  * Waveshare RP2040 Plus 16MB (waveshare_rp2040_plus@16mb)
