call reset_all_pins() in main() after port_init()

Before adafruit#10699, `reset_all_pins()` was called in `reset_port()`. That changed to reset all pins in main
after the finalizers ran. However, this mean that pins were not all reset on power-up or hard reset.
This caused adafruit#1841, because the power control pin for Feather S3 TFT was not powering the display as
required before the display was reset.

Add a call to `reset_all_pins()` early in `main()` to serve the same purpose.
