Add stack validity check and raise an error when it happens. 
The backtrace cannot be given because it relies on the validity
of the qstr data structures on the heap which may have been
corrupted.

In fact, it still can crash hard when the bytecode itself is
overwritten. To fix, we'd need a way to skip gathering the
backtrace completely.

This also increases the default stack size on M4s so it can
accomodate the stack needed by ASF4s nvm API.

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.

Ramp values to and from a default value while active. 
This reduces the popping sound on initial playback of an audio
sample.

The M4 DAC has a pop on startup that cannot be prevented. It also
does not allow readback so current values of the DAC are ignored.

Fixes #1090

Clock the SAMD21 much faster so it can actually convert at its max

Introduce displayio to render graphics to displays. 
It's designed to minimize RAM footprint by using Sprites to
represent objects on the screen. The object model also facilitates
partial screen updating which reduces the bandwidth needed to display.

This is all handled in C. Python simply manipulates the objects with
the ability to synchronize to frame timing.

Compress all translated strings with Huffman coding. 
This saves code space in builds which use link-time optimization.
The optimization drops the untranslated strings and replaces them
with a compressed_string_t struct. It can then be decompressed to
a c string.

Builds without LTO work as well but include both untranslated
strings and compressed strings.

This work could be expanded to include QSTRs and loaded strings if
a compress method is added to C. Its tracked in #531.
