Why I'm doing:
In shared UDF the function context object is cached in memory, this can lead to a UAF when accessing the function context, resulting in undefined behavior.
What I'm doing:
In this commit, we remove the Function Context object of BatchCallStub. Use the StatusOr interface instead of the control flow.
