Initial Grand Central definition It has a ton of pins in a Mega form-factor This also includes a change to init the stack earlier. It fixes a crash that occurs if the flash doesn't start correctly and the original spot isn't reached.

// This is for Rev B which is green and has the SD card slot at the edge of the board.

Rework safe mode and have heap overwrite trigger it. This creates a common safe mode mechanic that ports can share. As a result, the nRF52 now has safe mode support as well. The common safe mode adds a 700ms delay at startup where a reset during that window will cause a reset into safe mode. This window is designated by a yellow status pixel and flashing the single led three times. A couple NeoPixel fixes are included for the nRF52 as well. Fixes #1034. Fixes #990. Fixes #615.

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.
