Additional missing-prototypes fixes
I think this correctly enables missing-prototypes in atmel-samd
and raspberrypi ports.

Switch to pin, frequency and duty_cycle PulseOut
Passing in a PWMOut still works but is deprecated. It will be
removed in CircuitPython 8.0.0

This also switches STM32 timer indices and channel indices to
0-based in our pin data rather than `- 1` everywhere. The latter is
more bug prone.

Most of the way for #3264

Tested on Metro M0, Metro M4, Feather S2, Feather nRF52840, Feather
STM32F4 and Arduino RP2040.

Jeff Epler dfa7c3d32d codeformat: Fix handling of `**`
After discussing with danh, I noticed that `a/**/b` would not match `a/b`.

After correcting this and re-running "pre-commit run --all", additional
files were reindented, including the codeformat script itself.

Jeff Epler 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

Split pulseio.PWMOut into pwmio
This gives us better granularity when implementing new ports because

Jeff Epler dddd25a776 Combine similar strings to reduce size of translations
This is a slight trade-off with code size, in places where a "_varg"
mp_raise variant is now used.  The net savings on trinket_m0 is
just 32 bytes.

It also means that the translation will include the original English
text, and cannot be translated.  These are usually names of Python
types such as int, set, or dict or special values such as "inf" or
"Nan".

Rework sleep timing
It didn't account for background task time and could end up
sleeping for way longer than it should because the RTC compare time

Track unadjusted PWM duty cycle to avoid accumulating conversion errors
Fixes #2086

When the frequency of a `PWMOut` is change it re-sets the PWM's duty cycle as
well, since the registers have to be re-calculated based on the new frequency.
Unfortunately, `common_hal_pulseio_pwmout_get_duty_cycle`
will return a value very close to, but not exactly, the value passed to `common_hal_pulseio_pwmout_set_duty_cycle`. If the frequency is modified
without the calling code also re-setting the duty cycle then the duty cycle
will decay over time. This fixes that problem by tracking the unadjusted duty
cycle and re-setting the duty cycle to that value when the frequency is changed.
