Change unicode lookup tables to have int32 elements to support platforms where sizeof(int) < 4 (#23433)

Fixes an issue that comes up when using strutils.`%` or any other
strutils/strformat feature that uses the unicode lookup tables behind
the scenes, on systems where ints are than 32-bit wide.

Tested with:

```bash
./koch test cat lib
```

Refer to the discussion in #23125.
