…SparkR

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

This PR proposes to set the minimum Arrow version as 0.15.1 to be consistent with PySpark side at.

### Why are the changes needed?

It will reduce the maintenance overhead to match the Arrow versions, and minimize the supported range. SparkR Arrow optimization is experimental yet.

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

No, it's the change in unreleased branches only.

### How was this patch tested?

0.15.x was already tested at SPARK-29378, and we're testing the latest version of SparkR currently in AppVeyor. I already manually tested too.

Closes apache#28520 from HyukjinKwon/SPARK-31701.
