Move atmel-samd to tinyusb and support nRF flash. This started while adding USB MIDI support (and descriptor support is in this change.) When seeing that I'd have to implement the MIDI class logic twice, once for atmel-samd and once for nrf, I decided to refactor the USB stack so its shared across ports. This has led to a number of changes that remove items from the ports folder and move them into supervisor. Furthermore, we had external SPI flash support for nrf pending so I factored out the connection between the usb stack and the flash API as well. This PR also includes the QSPI support for nRF.

Fix QSPI on Feather nRF52840 We were writing with quad page program including the address (0x38) which is unsupported by the GD25Q16C but it is supported by the flash on the DK. So, we use the single address, quad data command (0x32).
