[SPARK-15108] [SQL] Describe Permanent UDTF
#### What changes were proposed in this pull request?
When Describe a UDTF, the command returns a wrong result. The command is
unable to find the function, which has been created and cataloged in the
catalog but not in the functionRegistry.
This PR is to correct it. If the function is not in the functionRegistry,
we will check the catalog for collecting the information of the UDTF function.
#### How was this patch tested?
Added test cases to verify the results
