Description

Comet need to support deterministic expressions in explode to match Spark

```
java.lang.RuntimeException: Error executing SQL 'SELECT id, explode(array(rand(0))) FROM test_explode_int WHERE id = 1' nondeterministic expressions are only allowed in Project, Filter, Aggregate or Window, found:
explode(array(rand(0))),col
in operator Generate explode(array(rand(0))), false, [col#93426].; line 1 pos 0;
```
However the test passed in pure Spark

The same needs to be tested for `explode/posexplode` for regular and outer variants
