fix(aco): deserialize nested types inside Option

When deserialize_option constructs a sub-deserializer to parse
the Some value, it was inheriting top_level from its parent.
For fields inside a struct or map, the parent's top_level is
false, causing the sub-deserializer to mistakenly treat its
resolved input as a reference ID that needs to be dereferenced.

Fix this by setting top_level to true when creating the
sub-deserializer inside deserialize_option. Also add a test
case to cover this scenario.
