[Core] Update mpaland/printf to eyalroz/printf fork (#16163)

Browse source 
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
