bd6826496c Fix various RP2040 audio dma things: (see detailed commit message) 
1. Check for correct error values from dma_claim_unused_channel.
2. Introduce a .stereo flag for simplicity.
3. Clarify PWM carrier frequency choice.
4. Start introducing quiescent audio value. Still need to ramp up/down.
5. Redo audio stop logic a bit.
6. Fix (unrelated) displayio dependency things.

There is still an interference problem between other DMA users and audio. Still debugging this.

Simplify the status LED to save power 
This also removes the need to pin share because we don't use the
status LED while user code is running.

The status flashes fallback to the HW_STATUS LED if no RGB LED is
present. Each status has a unique blink pattern as well.

One caveat is the REPL state. In order to not pin share, we set the
RGB color once. PWM and single color will be shutoff immediately but
DotStars and NeoPixels will hold the color until the user overrides
it.

Fixes #4133

e95e921ca1 codeformat: Fix filename matching 
In #4683, tannewt noticed that uncrustify was not running on some
file in common-hal.

I investigated and found that it was not being run on a bunch of paths.

Rather than make incremental changes, I rewrote list_files to work
bsaed on regular expressions; these regular expressions are created from
the same git-style glob patterns.

I spot-checked some specific filenames after this change, and all looks good:

```
$ python3 tools/codeformat.py -v --dry-run tests/basics/int_small.py ports/raspberrypi/common-hal/pulseio/PulseIn.c extmod/virtpin.c tests/thread/thread_exit1.py  ports/raspberrypi/background.h extmod/re1.5/recursiveloop.c
tools/codeformat.py -v --dry-run tests/basics/int_small.py ports/raspberrypi/common-hal/pulseio/PulseIn.c extmod/virtpin.c tests/thread/thread_exit1.py ports/raspberrypi/background.h extmod/re1.5/recursiveloop.c
uncrustify -c /home/jepler/src/circuitpython/tools/uncrustify.cfg -lC --no-backup extmod/virtpin.c ports/raspberrypi/background.h ports/raspberrypi/common-hal/pulseio/PulseIn.c
black --fast --line-length=99 -v tests/thread/thread_exit1.py
```
recursiveloop and int_small are excluded, while PulseIn, virtpin,
and background are included.

Testing running from a subdirectory (not _specifically_ supported though):
```
(cd ports && python3 ../tools/codeformat.py -v --dry-run raspberrypi/common-hal/pulseio/PulseIn.c ../extmod/virtpin.c)
../tools/codeformat.py -v --dry-run raspberrypi/common-hal/pulseio/PulseIn.c ../extmod/virtpin.c
uncrustify -c /home/jepler/src/circuitpython/tools/uncrustify.cfg -lC --no-backup ../extmod/virtpin.c raspberrypi/common-hal/pulseio/PulseIn.
```

As a side-effect, a bunch more files are re-formatted now. :-P

b8d4f9655f RP2040: Only bitbang 0-byte writes 
The I2C.c for RP2040 included a special case for writes <=2 bytes to match the MicroPython implementation,
however RP2040 does support 1 and 2 byte reads, with only 0 bytes being the exception.

16bfe3b41c raspberrypi: RTC: Ensure a time is set 
Until a time is set, the RTC is not running, and rtc_get_datetime()
returns false without assigning to the out-parameter.

In CircuitPython, this would manifest as arbitrary values being returned,
since uninitialized storage on the stack was being converted into a timestamp.

2ae1e7de61 WIPrp2040: Implement IncrementalEncoder 
Any two consecutive pins can be used for an IncrementalEncoder

Testing performed: Put a synthesized (few hundred counts per second) quadrature signal into GP2/3 and read the encoder out.  Performed filesystem operations at the same time to stress test it.

The reasons for not using common_hal_rp2pio_statemachine_readinto are commented on.

A few minor fixes for corner cases 
* Always clear the peripheral interrupt so we don't hang when full
* Store the ringbuf in the object so it gets collected when we're alive
* Make UART objects have a finaliser so they are deinit when their
  memory is freed
* Copy bytes into the ringbuf from the FIFO after we read to ensure
  the interrupt is enabled ASAP
* Copy bytes into the ringbuf from the FIFO before measuring our
  rx available because the interrupt is based on a threshold (not
  > 0). For example, a single byte won't trigger an interrupt.

Add state machine divisor check 
This causes an exception when setting a state machine too slow or

Implement audiobusio and enhance PIO for it 
This adds I2SOut and PDMIn support via PIO.

StateMachines can now:
 * read and read while writing
 * transfer in 1, 2 or 4 byte increments
 * init pins based on expected defaults automatically
 * be stopped and restarted
 * rxfifo can be cleared and rxstalls detected (good for tracking when
   the reading code isn't keeping up)

Fixes #4162
