Generate name-token slots from [NameSlot] string properties

A [NameSlot("role")] partial string property makes the generator own the
backing Identifier token slot, the string accessor, and the match term, so a
convenience name string and its hand-written token slot collapse to a single
declaration. A nullOnEmpty option stores a null token for an empty name, used
where the output visitor keys off an absent token. Apply it across every
name-token node.
