[libc-commits] [libc] [libc] Add dependency <stdint.h> to src/string/string_utils.h (PR #149849)

[William Huynh via libc-commits]

https://github.com/saturn691 created https://github.com/llvm/llvm-project/pull/149849

string_utils.h uses uintptr_t, and there seems to be no tracking of this dependency. It seems upstream builds are unaffected but downstream this is causing a lot of flaky builds.
