ORC-2131: Set default of orc.stripe.size.check.ratio and orc.dictionary.max.size.bytes to 0

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

Set default of `orc.stripe.size.check.ratio` and `orc.dictionary.max.size.bytes` to 0

### Why are the changes needed?

After enabling the optimizations related to orc.stripe.size.check.ratio and orc.dictionary.max.size.bytes, we observed that ORC files written with the current defaults are about 10%–20% larger than before. For example, datasets that were previously ~1.0–1.1 TB grow to ~1.2 TB with the current defaults, causing noticeable storage cost increase.

### How was this patch tested?
Local test

With orc.dictionary.max.size.bytes=16777216 or orc.stripe.size.check.ratio=2.0, the written ORC data grows to 1.2 TB (data inflation).

```shell
           1         6665      1300347279057 hdfs://ns/user/hive/warehouse/tmp_sandbox_xxx.db/tmp_test_123_2/d=2026-03-15
```

With orc.dictionary.max.size.bytes=0 and orc.stripe.size.check.ratio=0.0, the data size remains at the expected 1.0 TB.
```shell
           1         6665      1143347882367 hdfs://ns/user/hive/warehouse/tmp_sandbox_xxx.db/tmp_test_123_1/d=2026-03-15
```
