GH-102711: Fix warnings found by clang

[parheliamm]

There are some warnings if build python via clang:

/home/lge/rpmbuild/BUILD/Python-3.10.9/Parser/pegen.c:812:31: warning: a function declaration without a prototype is deprecated in all versions of C [-Wstrict-prototypes]
_PyPegen_clear_memo_statistics()
^
void
/home/lge/rpmbuild/BUILD/Python-3.10.9/Parser/pegen.c:820:29: warning: a function declaration without a prototype is deprecated in all versions of C [-Wstrict-prototypes]
_PyPegen_get_memo_statistics()
^
void

Fix it to make clang happy.

This looks fine and is analogous to e35ca41 / #99086.

Sorry, @parheliamm and @ambv, I could not cleanly backport this to 3.9 due to a conflict.
Please backport using cherry_picker on command line.
cherry_picker 7703def37e4fa7d25c3d23756de8f527daa4e165 3.9

[ambv]

Actually, forget about the 3.9 backport as this isn't security-related.
