Update tinyusb, drive EN pin on boost converter

Updates TinyUSB with the latest upstream changes and makes it so that
pin 18 is driven high on the Feather USB Host board (connected to the
enable pin on the boost converter supplying 5V to connected USB
devices).

Please note there has been some confusing renaming of the Pico-PIO-USB
related pin defines in TinyUSB.
