Conditionally set variables such as the softdevice RAM size, bootloader
size, and the spi m3 buffer size. This allows ports to adjust these
values to suit their needs.

The BLE Config area needs to be subtracted from the size of the firmware.
THis is because the firmware is counted by walking backwards from the end
of memory, and the BLE config area is placed lower in memory than the
firmware. Subtracting the BLE config size ensures the internal flash
filesystem doesn't try to use the firmware as storage.

This adds preliminary support for the nRF52833, which is a variant of
the nRF52840 with half the RAM, half the flash, and fewer peripherals.

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.
This was the last class from ubluepy and so that module is now gone.
The Device class offers both Peripheral and Central functionality.
