Fix ticks
In #7497 port_background_task was renamed to port_background_tick
but the actual call site wasn't changed. This meant that it was
no longer called!

Rename more functions from task to tick to make it clearer which is
which.

mimxrt: Fix output frequency for samples that don't divide 192kHz
This makes all the samples from Dan's collection register as 440Hz
when playing on pwmio or i2sout, using https://webaudiodemos.appspot.com/pitchdetect/index.html
to detect the frequency played (all should show as A 440Hz; an error
of up to 20 "cents" should be treated as OK)

There's an audible carrier with PWM output and the 8kHz samples. This is
probably a limitation of the peripheral which is documented as being for
input signals of 44 kHz or 48 kHz; the carrier frequency is a fixed
multiple of the sample frequency.

Closes #7800

mimxrt10xx: Add PWMAudioOut
.. via a peripheral known as the "MQS" (medium quality sound). It uses an
~192kHz PWM signal to generate audio. It sounds OK on a small speaker with
no amplifier. There's a small pop when starting/stopping audio, as is
typical.

Add IncrementalEncoder for mimxrt1011
.. and write a general 'pin change interrupt' facility to power it

This uses the same quadrature state machine as atmel-samd, nrf, and
rp2040. The 1011 doesn't have a dedicated encoder peripheral, so we
go the pin-change + software route.

mimxrt10xx: implement i2sout
tested on metro m7 (green prototype version) with max98357a i2s amplifier and the following test code:
```py
import board
import time
import digitalio
from audiobusio import I2SOut
from audiocore import RawSample
from microcontroller import pin
from ulab import numpy as np

n = np.array(np.sin(np.linspace(0, np.pi*2, 218, endpoint=False)) * 200, dtype=np.int16)
print(n)
r = RawSample(n, sample_rate=8000, channel_count=2)
def main():
    with digitalio.DigitalInOut(board.LED) as l:
        l.switch_to_output(True)
        value = False
        while True:
            with I2SOut(pin.GPIO_06, pin.GPIO_07, pin.GPIO_04) as i:
                time.sleep(.01)
                l.value = value = not value
                i.play(r, loop=True)
                print(i.playing)
                time.sleep(.5)
                i.stop()
                print("STOPPED")
                print(i.playing)
                time.sleep(.5)
                i.play(r, loop=True)
                print(i.playing)
                print("PLAY AGAIN")
                time.sleep(.5)
            time.sleep(1)
```

Only stereo, 16-bit, raw samples were tested; the sample rate is actually fixed
at 48kHz in the core right now. There is more to do, but the basics work.

Improve iMX RT performance
* Enable dcache for OCRAM where the VM heap lives.
* Add CIRCUITPY_SWO_TRACE for pushing program counters out over the
  SWO pin via the ITM module in the CPU. Exempt some functions from
  instrumentation to reduce traffic and allow inlining.
* Place more functions in ITCM to handle errors using code in RAM-only
  and speed up CP.
* Use SET and CLEAR registers for digitalio. The SDK does read, mask
  and write.
* Switch to 2MiB reserved for CircuitPython code. Up from 1MiB.
* Run USB interrupts during flash erase and write.
* Allow storage writes from CP if the USB drive is disabled.
* Get perf bench tests running on CircuitPython and increase timeouts
  so it works when instrumentation is active.

use right DBL_TAP_REG when resetting to bootloader
This helps my development scripts work better, and probably also fixes
a problem switching from the circuitpython environment back to arduino.
(specifically, the "1200 baud" serial trick was not rebooting into
the bootloader but was just resetting)

Fix `pwmio` on iMX RT.
It now handles deinit, never_reset and sharing tracking. PWM
now runs in the WAIT state as well during a time.sleep().

_reset_ok() was removed because it was called in one spot right
before deinit().

Some PWMOut were also switched to a bitmap for use instead of
reference count. That way init and deinit are idempotent.

Fixes #6589. Fixes #4841. Fixes #4541.

Add Bangle.js 2, JDI memory displays and ACeP epd
This 2-in-1 PR started with the goal of support the Bangle.js 2
smartwatch with *no USB*.
* Adds "secure" DFU build support with a committed private key.
* Adds 3-bit color support with one dummy bit for the JDI memory display
* Allows nrf boards to have a board_background_task() run in RUN_BACKGROUND_TASK.
  This is needed because the Bangle.js 2 uses the watchdog to reset.
* Renamed port_background_task() to port_background_tick() to indicate it
  runs on tick, not RUN_BACKGROUND_TASK.
* Marks serial connected when the display terminal is inited. This means
  that safe mode messages show up on the display.

ACep, 7-color epaper displays also pack 3 bits in 4. So, I added that
support as well.
* Adds 3-bit ACeP color support for 7-color e-paper displays. (Not
  watch related but similar due to color depth.)
* Allows a refresh sequence instead of a single int command. The 7" ACeP
  display requires a data byte for refresh.
* Adds optional delay after resetting the display. The ACeP displays
  need this. (Probably to load LUTs from flash.)
* Adds a cleaning phase for ACeP displays before the real refresh.

For both:
* Add dither support to Palette.
* Palette no longer converts colors when set. Instead, it caches
  converted colors at each index.
* ColorConverter now caches the last converted color. It should make
  conversions faster for repeated colors (not dithering.)
