AVRO-4242: [Java] Fix NPE in DataFileStream and DataFileReader when schema
metadata is missing
Malformed Avro container files without the 'avro.schema' metadata entry
caused a NullPointerException in both DataFileStream and DataFileReader12
when the null value was passed directly to Schema.Parser.parse(). Replace
inline parsing with null-safe helper methods that throw a descriptive
IOException instead.
> Malformed Avro container without schema metadata should fail graciously
