[SPARK-20918] [SQL] Use FunctionIdentifier as function identifiers in
FunctionRegistry

Currently, the unquoted string of a function identifier is being used as
the function identifier in the function registry. This could cause the
incorrect the behavior when users use `.` in the function names. This PR is to
take the `FunctionIdentifier` as the identifier in the function registry.
### How was this patch tested?
TODO: add extra test cases to verify the inclusive bug fixes.
