[SPARK-52660][SQL] Add time type to CodeGenerator#javaClass

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

Update `CodeGenerator#javaClass` to map `TimeType` to `Long`.

### Why are the changes needed?

The change is needed to fully support wholestage codegen for code using the time type. Without this change, the following query gets an error compiling the generated code (and falls back to non-wholestage codegen):
```
create or replace temp view v1(col1) as values
(time'22:33:01'),
(time'01:33:01'),
(null);

select max(col1), min(col1) from v1;
```
### Does this PR introduce _any_ user-facing change?

No. The time type is not released yet.

### How was this patch tested?

New test.

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

No.

Closes apache#51354 from bersprockets/time_agg_issue.
