[roll] Roll fuchsia [network] std::sync -> fuchsia_sync
The behaviors of fuchsia_sync's locks are very similar to those from
the standard library. std::sync::Mutex is a port of the libsync
mutex that fuchsia_sync::Mutex links against, and fuchsia_sync::RwLock
is very similar to the std::sync::RwLock's futex-based approach. However
there are some important differences:
1. fuchsia_sync supports lock cycle detection which surfaces many
deadlocks. See the documentation[0] for more details.
2. fuchsia_sync doesn't support lock poisoning because most of
Fuchsia's code is compiled with panic=abort.
a. saves memory with smaller types
b. avoids noop error handling syntax and branches
