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

[bersprockets]

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.

Thank you, @bersprockets and @yaooqinn for review.

By the way, there are a couple more like this (that is, match expressions that need a case statement for the Time type). I will work though them separately, as they are for different bits of Spark SQL (e.g., interpreted mode projections, caching, and a few other odds and ends).

Thank you for checking them thoroughly. Feel free to make small PRs (case by case), @bersprockets .
