[SPARK-48185][SQL] Fix 'symbolic reference class is not accessible: class sun.util.calendar.ZoneInfo'

### What changes were proposed in this pull request?

I met the error below while debugging UTs because of loading `sun.util.calendar.ZoneInfo` eagerly. This PR makes the relevant variables lazy.

```log
Caused by: java.lang.IllegalAccessException: symbolic reference class is not accessible: class sun.util.calendar.ZoneInfo, from interface org.apache.spark.sql.catalyst.util.SparkDateTimeUtils (unnamed module 65d6b83b)
	at java.base/java.lang.invoke.MemberName.makeAccessException(MemberName.java:955)
	at java.base/java.lang.invoke.MethodHandles$Lookup.checkSymbolicClass(MethodHandles.java:3686)

```

### Why are the changes needed?

sun.util.calendar.ZoneInfo is inaccessible in some scenarios.

### Does this PR introduce _any_ user-facing change?

Yes, such errors might be delayed from backend-scheduling to job-scheduling

### How was this patch tested?

I tested with idea and UT debugging locally

### Was this patch authored or co-authored using generative AI tooling?

no

Closes #46457 from yaooqinn/SPARK-48185.
