pythongh-99086: Further -Wstrict-prototypes, -Wimplicit-function-decl…

…aration fixes Followup to 12078e7. I ended up missing a few, apparently. Clang 16 makes -Wimplicit-function-declaration an error by default and warns on -Wstrict-prototypes. It's free to fix -Wstrict-prototypes while we're here and it futureproofs us, so throw that in. The only notable part of this which might not be super obvious is <stddef.h> for size_t.
