Generates an atomic bitset wrapper over [AtomicBitSet].

Two forms are supported, mirroring bitflagset!:

• Enum form: atomic_bitflagset!(pub struct AtomicMySet(AtomicU8) on MySet);
• Position form: atomic_bitflagset! { pub struct AtomicMyFlags(AtomicU8) on MyFlags { const A = 0; } }

Methods that mutate bits take &self (atomic interior mutability).
