Subject: [PATCH] [SPARK-36043][SQL][TESTS] Add end-to-end tests with default
 timestamp type as TIMESTAMP_NTZ

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

Run end-to-end tests with default timestamp type as TIMESTAMP_NTZ to increase test coverage.

### Why are the changes needed?

Inrease test coverage.
Also, there will be more and more expressions have different behaviors when the default timestamp type is TIMESTAMP_NTZ, for example, `to_timestamp`, `from_json`, `from_csv`, and so on. Having this new test suite helps future developments.

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

No

### How was this patch tested?

CI tests.

Closes #33259 from gengliangwang/ntzTest.
