docgen relies on the convention that we have a file foo.cpp in libc/src/\<header\>/. Because the above functions weren't in libc/src/strings/ but rather libc/src/string/, docgen could not find that we had implemented these. Rather than add special carve outs to docgen, let's fix up our sources for these 7 functions to stick with the existing conventions the rest of the codebase follows. Link: #118860 Fixes: #118875
