Fix SAMD
RTC needed to wait for sync. NeoPixel on SAMD doesn't need disabled
caches. It just needed timing adjustment for 120mhz clock speed.

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

dfa7c3d32d codeformat: Fix handling of **

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

ff1942cff6 Enable protomatter on RP2040 builds
Also found a race condition between timer_disable and redraw, which
would happen if I debugger-paused inside common_hal_rgbmatrix_timer_disable
or put a delay or print inside it.  That's what pausing inside reconstruct
fixes.

So that the "right timer" can be chosen, `timer_allocate` now gets the `self`
pointer.  It's guaranteed at this point that the pin information is accurate,
so you can e.g., find a PWM unit related to the pins themselves.
This required touching each port to add the parameter even though it's
unused everywhere but raspberrypi.

Add board_deinit for use with sleep
This changes lots of files to unify `board.h` across ports. It adds
`board_deinit` when CIRCUITPY_ALARM is set. `main.c` uses it to
deinit the board before deep sleeping (even when pretending.)

Deep sleep is now a two step process for the port. First, the
port should prepare to deep sleep based on the given alarms. It
should set alarms for both deep and pretend sleep. In particular,
the pretend versions should be set immediately so that we don't
miss an alarm as we shutdown. These alarms should also wake from
`port_idle_until_interrupt` which is used when pretending to deep
sleep.

Second, when real deep sleeping, `alarm_enter_deep_sleep` is called.
The port should set any alarms it didn't during prepare based on
data it saved internally during prepare.

ESP32-S2 sleep is a bit reorganized to locate more logic with
TimeAlarm. This will help it scale to more alarm types.

b227b79dec Fix #3504: Don't use time module in pew.tick()
The time.sleep() and time.monotonic() functions break the timer
interrupt on which PewPew10 display relies, so we can't use them
anymore. Instead I'm adding a time-keeping function to the display
code itself, which then can be used in pew.tick() internally.

45eec5b5a5 samd: SPI: improve conditional code
I recently misdiagnosed a "maybe-uninitialized" diagnostic as a bug in
asf4.  However, the problem was in our SPI code.

A special case for samr21 MCUs was being applied to same54p20a and possibly
other D5x/E5x MCUs, since the check was simply for pin PC19 existing at all.

Change the check to use the macro PIN_PC19F_SERCOM4_PAD0 which is only
defined if special function F of pin PC19 is SERCOM4 PAD0.

Reorganize the code a little bit so that brace-matching in editors is
not confused by the conditionalized code, including an unrelated change
for APA102_SCK's condition.

Revert the change to the Makefile that incorrectly attempted to silence
the diagnostic.

a580f0f1c4 _pew: move to common-hal
I noticed that this code was referring to samd-specific functionality,
and isn't enabled except in one samd board (pewpew10).  Move it.

There is incomplte support for _pew in mimxrt10xx which then caused build
errors; adding a #if guard to check for _pew being enabled fixes it.
The _pew module is not likely to be important on mimxrt but I'll leave the
choice to remove it to someone else.

eb3d5fa453 ujson: do not eat trailing whitespace
Ujson should only worry about whitespace before JSON.  This becomes apparent when you are using MP stream protocol to read directly from input buffers.

When you attempt to read(1) on a UART (and possibly other protocols) you have to wait for either the byte or the timeout.

Fixes:
- Waiting for a timeout after you have completed reading a correct and complete JSON off the input.
- Raising an OSError after reading a correct and complete JSON off the input.
- Eating more data than semantically owned off the input buffer.
- Blocking to start parsing JSON until the entire JSON body has been loaded into a potentially large, contiguous Python object.

Code you would write before:
```
line = board_busio_uart_port.read_line()
json_dict = json.loads(line)
```
or reaching for fixed buffers and swapping them around in Python.

Code that did not work before that does now:
```
json_dict = json.load(board_busio_uart_port)
```

- This removes the need for intermediate copies of data when reading JSON from micropython stream protocol inputs.
- It also increases total application speed by parsing JSON concurrently with receiving on boards that read from UART via DMA.
- It simplifies code that users write while improving their apps.

5fcc6d6286 RGBMatrix: finish renaming from Protomatter
This gets all the purely internal references.  Some uses of
protomatter/Protomatter/PROTOMATTER remain, as they are references
to symbols in the Protomatter C library itself.

a32337718d Rename _protomatter -> protomatter
I originally believed that there would be a wrapper library around it,
like with _pixelbuf; but this proves not to be the case, as there's
too little for the library to do.

It didn't account for background task time and could end up
