19027: sys/fmt: optimize scn_u32_dec scn_u32_hex r=benpicco a=kfessel
### Contribution description
Improves the compilation result for `scn_u32_dec` `scn_u32_hex` especially on `cortex-m` reducing either stack usage and or code size.
This makes use of unsigned int overflow (slightly less better without doing that `hexn`).
See godbolt (original versions got an `o` attached, modified versions got `k`s) all functions are marked `_S_` defined to `static`
by assigning the global at end the compiled function can be changed (`deco deck hexo hexk hexkk hexn`)
this PR is `hexkk` and `deck`
### Testing procedure
run unit-test/test-fmt
```
<RIOT>/tests/unittests$ make tests-fmt
<RIOT>/tests/unittests$ make term
```

sys/fmt: fix interaction with stdio
...
Use fwrite instead of write to not bypass caching stdio. Other fmt's
print function are too much of a footgun to use.
