alif/tinyusb_port: Fix setting of USB device addr for fast hosts.

A fast host (eg Mac M4) may request the status for the SET_ADDRESS before
TinyUSB gets to process it.  This is because TinyUSB does not handle events
inside the USB ISR, rather it waits for the top-level thread to process
them.  Fix that by setting the USB device address as soon as
TUSB_REQ_SET_ADDRESS comes in.

This patch follows the corresponding upstream fix:
alifsemi/tinyusb@fc40ea7
