A safe mode fix and displayio fixes
* Fixes safe mode on the SAMD51. The "preserved" value was being
clobbered by the bootloader.
* Fixes auto-reload loop when in safe mode.
* Fixes reading Group children with [].
* Check that a TileGrid actually moves before queueing a refresh.

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.

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.

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.

e580d22f4a Use the external crystal on SAMD21 again.
Also, re-enable calibration storage for CircuitPlayground Express.
Tested with a 500hz PWMOut on Metro M0 with Saleae:
 * with crystal 500hz
 * with usb 500hz +- 0.1hz
 * without either 487hz += 0.1hz

SAMD51 is skipped due to DFLL errata and the fact it defaults to a
factory calibrated 48mhz that works fine for USB.

ab7ddfddd5 atmel-samd/samd51: Refactor clock setup
Refactor the convoluted asf4 clock setup into something more readable.

enable_clock_generator() has 2 changes:
- Set 'Output enabled' to match the current clock setup
- Handle divisors above 511

Add an enable_clock_generator_sync() version which makes it possible to setup
clocks without waiting for syncing. The bootup would hang without this.

I have checked these registers:

 NVMCTRL->CTRLA = 0x00000004

 Peripheral clocks (only non-zero shown):
 PCHCTRL[1]=0x00000045
 PCHCTRL[10]=0x00000041

 Generator clocks (only non-zero shown):
 GENCTRL[0] = 0x00010907
 GENCTRL[1] = 0x00010906
-GENCTRL[2] = 0x00041104
+GENCTRL[2] = 0x00200904
 GENCTRL[4] = 0x00010907
 GENCTRL[5] = 0x00180906

 DFLL clock:
 OSCCTRL->DFLLCTRLA = 0x00000082
 OSCCTRL->DFLLCTRLB = 0x00000000
 OSCCTRL->DFLLVAL = 0x00008082
 OSCCTRL->DFLLMUL = 0x00000000

 DPLL clocks:
 OSCCTRL->Dpll[0].DPLLCTRLA=0x00000002
 OSCCTRL->Dpll[0].DPLLCTRLB=0x00000000
 OSCCTRL->Dpll[0].DPLLRATIO=0x0000003b
 OSCCTRL->Dpll[1].DPLLCTRLA=0x00000080
 OSCCTRL->Dpll[1].DPLLCTRLB=0x00000020
 OSCCTRL->Dpll[1].DPLLRATIO=0x00000000

 OSC32KCTRL clock:
 OSC32KCTRL->RTCCTRL = 0x00000000
 OSC32KCTRL->XOSC32K = 0x00002082
 OSC32KCTRL->CFDCTRL = 0x00000000
 OSC32KCTRL->EVCTRL = 0x00000000
 OSC32KCTRL->OSCULP32K = 0x00002300

Only gen2 changed which is due to samd51 having more bits in the simple
division register so DIVSEL wasn't necessary, and it didn't have OE set.

4adba51569 atmel-samd/samd21: Rework clock setup
Make clock setup explicit instead of using the convoluted asf4 macro setup.

enable_clock_generator():
- Add GCLK_GENCTRL_OE to stick with the current setup.
- Handle divisor larger than 31 for generator 2
- Change the source argument so it can take the GCLK_GENCTRL_SRC_XXXX_Val
  macros without casting to uint8_t.

This patch should not introduce any functional changes except keeping
GCLK_GENCTRL_OE enabled when the I2S clock is enabled.

28642ab10d Add audio output support!
This evolves the API from 2.x (and breaks it). Playback devices are now
separate from the samples themselves. This allows for greater playback
flexibility. Two sample sources are audioio.RawSample and audioio.WaveFile.
They can both be mono or stereo. They can be output to audioio.AudioOut or
audiobusio.I2SOut.

Internally, the dma tracking has changed from a TC counting block transfers
to an interrupt generated by the block event sent to the EVSYS. This reduces
the overhead of each DMA transfer so multiple can occure without using up TCs.

Fixes #652. Fixes #522. Huge progress on #263
