util: Add string utils

[Nitr4m12]

These are a bunch of functions I've found digging through DWARF info. In order to match, I decompiled a couple of functions that used them since all of them are inlined and are very much defined in the header. The games I checked with were Splatoon 2 (nw 1.6.0), SMO (nw 3.5.1) and Bloons TD 5 (nw 5.3.0).

Please run clang-format there is some trailling whitespaces in your code.

Where did you find these functions? I can't find them in SMO's SDK nor in MK8DX's SDK.

Please use types from <nn/types.h>
int -> s32

Done

These are from BTD5's debug build. They are inlined when used so they're not exported, and are only present in the DWARF info of the debug build (from what I can tell).

The DWARF does not show them using typedefs, which is why I wasn't.
