GCC 13 needs the same workaround as GCC 12.
To avoid having to maintain an ever-growing list of broken versions
apply the workaround wherever it can be used.
If at some point a fixed version of GCC is released the workaround can
be disabled for those fixed versions.
See #17064
mpaland printf implementation was abandoned in ~2019 and the fork by
eyalroz is now regarded to be the goto replacement of it. So this commit
incoporates the changes needed to use this fork in QMK.
Note that pointer ptrdiff_t is always supported since commit
51c90f93a97fdaef895783ecbe24569be0db7cb8
* avr i2c_master: Fix 1ms timeout
i2c_start() produces a minimum time_slice of 1ms for use as timeout
value.
The timer granularity is 1ms, it is entirely possible for timer_count
to tick up immediately after the last timer read and falsely trigger
timeout with a '>= 1' comparison.
* avr/drivers/i2c_master: Use timer_elapsed()
* Fix platforms/avr/drivers/ws2812.c
`platforms/avr/drivers/ws2812.c` has been changed to use `DDRx_ADDRESS()` and `PORTx_ADDRESS()` instead of `_SFR_IO8()` in #8646. To use them, `#include <pin_defs.h>` is required.

* Add open-drain GPIO support.
* `qmk format-c`
* Wording.
* Remove port GPIO implementations as the only board that uses it has its own internal defs anyway. Will wait for first-class handling of ports in core before reimplementing.
