This count should mean the number of fields expected in the serialized form,
so if some fields are skipped, they shouldn't be counted
Methods affected:
- Deserializer::deserialize_tuple
- Deserializer::deserialize_tuple_struct

This works just fine if we make syn parse "where " as a syn::WhereClause.
The serde(bound = "") attribute is definitely not common enough that it
would warrant a micro-optimization.
This function is called for untagged, internally and externally tagged enums,
but `deserializer` parameter is `None` only for the latest. Only when it's `None`
`DeserializeSeed` impl is used
