Subject: [PATCH] Add size_t to u32 static_casts to irrString

The irrString implementation doesn't allow constructing a string with a
size that would exceed a u32, so it should be safe to narrow the size of
the underlying STL container back to a u32.

This fixes 5 narrowing cast warnings from Visual Studio 17 2022.
