Fix running the USB task on nRF. 
It wasn't being run due to a rework done only on the atmel-samd port.
The rework itself isn't needed now that the heap check triggers safe
mode instead of throwing a Python exception. So, I've removed the
rework.

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.

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.

1b86e5fc83 samd51: Enable functionality to support CPython stdlib 
This enables various things in order to support the CPython standard library.

MICROPY_PY_BUILTINS_NOTIMPLEMENTED:
Support NotImplemented for easy conversion of stdlib.
It doesn't do fallbacks though, only raises TypeError.

MICROPY_PY_COLLECTIONS_ORDEREDDICT:
collections.OrderedDict

MICROPY_PY_FUNCTION_ATTRS:
Support function.__name__ for use as key in the function attribute workaround.

MICROPY_PY_IO:
uio module: BytesIO, FileIO, StringIO, TextIOWrapper
Also add 'io' alias.

MICROPY_PY_REVERSE_SPECIAL_METHODS:
Support the __r*__ special methods.

MICROPY_PY_SYS_EXC_INFO:
sys.exc_info() used by unittest when collecting exceptions.

MICROPY_CPYTHON_COMPAT:
Some of the things it adds:

>>> object.__init__
<function>
>>> object.__new__
<function>
>>> object.__class__
<class 'type'>
>>> object().__class__
<class 'object'>
>>> object.__name__
'object'

>>> 'Hello'.encode()
b'Hello'
>>> b'Hello'.decode()
'Hello'

Named tuple field names from string:
namedtuple('Point', 'x y')

cec9a69a15 samd51: Make errno, os, and time module aliases 
Add alias for uerrno so the user doesn't have to know about the
CircuitPython special names for the module.

Make os and time weak modules (aliases) making it possible to add
functionality to those modules written in python.

Example:
'import os' will now look in the path for an os module and if not found
it will import the builtin module. An os module written in python will
import the builtin module through its name prefixed with an underscore
(_os) following the C module naming practice in CPython.

Also right align the macro values to increase readability making it
easier to compare the values for samd21 and samd51. Even the longest
macro from py/mpconfig.h will fit with this alignment.

Ramp values to and from a default value while active.

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.

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.

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.
