Should I squash the fixups and improve the commit messages a bit, or should I wait for more reviews? |

Feel free to squash |

Contribution description
As discussed in #20182, this PR adds custom print format specifiers for
size_t(e.g.,PRIuSIZE) that doesn't assumesizeof(unsigned) == sizeof(size_t)toarchitecture.hand changes thesize_tprinting recommendation inCODING_CONVENTIONS.mdFurthermore, the bulk of this PR consists of changes that modify print statements with
size_targuments to use the new print format specifiers.@maribu mentioned a possible switch to picolib in the near future. This would provide support for the currently problematic
%zformat specifier. If this is the preferred solution, I can easily replace thePRIuSIZE,PRIxSIZE, etc. macros with the corresponding%zmodifiers and remove the custom print format specifiers.Testing procedure
This shouldn't change any test or application.
To test the debug statement, set the appropriate
ENABLE_DEBUGmacro (or enable it globally).Issues/PRs references
