[SPARK-33733][SQL][3.0] PullOutNondeterministic should check and collect
deterministic field
backport [#30703](https://github.com/apache/spark/pull/30703) for
branch-3.0.
### What changes were proposed in this pull request?
The deterministic field is wider than `NonDerterministic`, we should keep
same range between pull out and check analysis.
### Why are the changes needed?
For example
```
select * from values(1), (4) as t(c1) order by
java_method('java.lang.Math', 'abs', c1)
```
We will get exception since `java_method` deterministic field is false but
not a `NonDeterministic`
```
Exception in thread "main" org.apache.spark.sql.AnalysisException:
nondeterministic expressions are only allowed in
Project, Filter, Aggregate or Window, found:
java_method('java.lang.Math', 'abs', t.`c1`) ASC NULLS FIRST
in operator Sort [java_method(java.lang.Math, abs, c1#1) ASC NULLS FIRST],
true
;;
```
### Does this PR introduce _any_ user-facing change?
Yes.
### How was this patch tested?
Add test.
Closes #30771 from ulysses-you/SPARK-33733-branch-3.0.
