[SPARK-14487][SQL] User Defined Type registration without
SQLUserDefinedType annotation
## What changes were proposed in this pull request?
JIRA: https://issues.apache.org/jira/browse/SPARK-14487
Currently we use `SQLUserDefinedType` annotation to register UDTs for user
classes. However, by doing this, we add Spark dependency to user classes.
For some user classes, it is unnecessary to add such dependency that will
increase deployment difficulty.
We should provide alternative approach to register UDTs for user classes
without `SQLUserDefinedType` annotation.
## How was this patch tested?
`UserDefinedTypeSuite`
