[KYUUBI #4899] [AUTHZ] Extract function from FunctionIdentifier for CreateFunction and DropFunction in Spark 3.4

### _Why are the changes needed?_

- adapting changes in logical plan of CreateFunction/DropFunction  in Spark 3.4 by extracting table object from `FunctionIdentifier`, to fix tests on Spark 3.4
  - ut "CreateFunctionCommand"
  - ut "DropFunctionCommand"

### _How was this patch tested?_
- [ ] Add some test cases that check the changes thoroughly including negative and positive cases if possible

- [ ] Add screenshots for manual tests if appropriate

- [x] [Run test](https://kyuubi.readthedocs.io/en/master/develop_tools/testing.html#running-tests) locally before make a pull request
