ARROW-6594: [Java] Support logical type encodings from Avro

Related to [ARROW-6594](https://issues.apache.org/jira/browse/ARROW-6594).

Avro supports some logical types that overlap with Arrow logical types (http://avro.apache.org/docs/current/spec.html#Logical+Types)

For the ones that overlap, we should use the appropriate Arrow Logical type array instead of the raw values.

Closes #5781 from tianchen92/ARROW-6594 and squashes the following commits:
