Enum mz_dyncfg::ConfigValAtomic

pub(crate) enum ConfigValAtomic {
    Bool(Arc<AtomicBool>),
    U32(Arc<AtomicU32>),
    Usize(Arc<AtomicUsize>),
    OptUsize(Arc<RwLock<Option<usize>>>),
    F64(Arc<AtomicU64>),
    String(Arc<RwLock<String>>),
    Duration(Arc<RwLock<Duration>>),
    Json(Arc<RwLock<Value>>),
}

An atomic version of ConfigVal to allow configuration values to be shared between configuration writers and readers.

TODO(cfg): Consider moving these Arcs to be a single one around the map in ConfigSet instead. That would mean less pointer-chasing in the common case, but would remove the possibility of amortizing the name lookup via Config::handle.
