`rpad` function causes OOM

[ZuoTiJia]

Describe the bug
When I use the rpad function, and the parameter of the rpad function is large, it causes OOM.
Does Datafusion have a mechanism to limit the resources required for execution.

To Reproduce

create table test(a bigint) as values
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1),
    (1), (1), (1), (1), (1);
select rpad('a', 1073741824, 'a') from test;

We probably have to put some limits. for example postgres fails fast

select rpad('a', 1073741824, 'a');

requested length too large

My Mac is spinning CPU like crazy with the same query in datafusion-cli, I had to kill the process

@ZuoTiJia is such kind of rpad is needed by your real use case or you testing DF limits? :)

Postgres handles this in very interesting manner

I'm testing DF and I think it's dangerous for users if there is no limit.

sounds good, I think we can implement quick win like in PG
https://github.com/postgres/postgres/blob/c8e1ba736b2b9e8c98d37a5b77c4ed31baf94147/src/include/utils/memutils.h#L42

I'll take this later this week unless no one else volunteers

It looks like the check is implemented https://github.com/apache/datafusion/blob/main/datafusion/functions/src/unicode/rpad.rs#L131
However, when I tried to run the above sql query, I got offset overflow error from /arrow-array-52.2.0/src/array/byte_array.rs:210:45.
Is that an OOM issue?
