Add cstdint header for gcc-15 compatibility

Common C++ headers (like <memory>) in GCC 15.0.0 (combined with libstdc++) don't transitively include uint64_t anymore.

Minimal reproducer: https://godbolt.org/z/dqGbnG8bY

Porting: https://github.com/ROCm/rocm_smi_lib/pull/198
Closes: https://github.com/ROCm/rocm_smi_lib/issues/191
