Fix a function serialization bug in AvroIO
Hi @jkff , can you please take a look?
If ValueProvider<String> is specified as outputPrefix, a
NestedValueProvider is created with a SerializableFunction enclosed to perform
some translation work.
However, in the original codes the function is created as an anonymous
class, capturing the enclosing class TypedWrite as "this", which contains a
un-serializable member Schema. An exception is thrown from expand() if run
because the function is not serializable.
