[C++][Gandiva] Refactor function holder to return arrow Result

[niyue]

Describe the enhancement requested

Gandiva FunctionHolder classes currently use output parameters to return the holder function, and it can be refactored to return arrow::Result instead of using output parameters, and this tries to address the follow up task mentioned in #38632 (comment) and makes the code slightly simpler
