Consequence: `FlattenSkipDeserializing[DenyUnknown]`
- does not collect data in Field, because do not read them anyway
- gets `deserialize_in_place` method
- gets ability to deserialize from sequence (visit_seq method)
- uses `deserialize_struct` instead of `deserialize_map`
- Fix incorrect deserialization of variants that doesn't contain flatten field when other contains
- Fix a panic when deriving `Deserialize` for an enum with tuple and struct with flatten field

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.
