[SPARK-14253][SQL] Refactor HiveFunctionRegistry for temporary functions
## What changes were proposed in this pull request?
This is a prerequisite to SPARK-14123, which implements DDLs related to
functions using `SessionCatalog`. In order to support `CREATE TEMPORARY
FUNCTION` we need a way to make a `FunctionBuilder` from the function class
name. This patch exposes an interface to do so.
## How was this patch tested?
Jenkins.

Expose makeFunctionBuilder in function registry
This allows the DDL commands (when we implement them later) to
use this to create a FunctionBuilder when calling SessionCatalog
methods. This is needed for temporary functions.
