The `#if` check only checks that `MICROPY_PY_NETWORK_CYW43` and `MICROPY_HW_PIN_EXT_COUNT` are defined. This is a reasonable assumption for the Pico W, but causes conflicts if someone wants to attach an external IO expander to their Pico W and have its pins appear as Pin objects. This commit addresses this by adding the additional checks, letting board builds include wireless but separately choose whether the external IO pins come from the cyw43 or not.
