blake3_dispatch: Fix race condition initializing g_cpu_features.
If multiple threads try to compute a hash simultaneously before the library has been used for the first time,
the logic in get_cpu_features that detects CPU features will write to g_cpu_features without synchronization,
which is a race condition and flagged by ThreadSanitizer.
This change marks g_cpu_features as an atomic variable to address the race condition.
