feat: zero-copy columnar conversion for ArrowColumnVector-backed batches

[tokoko]

Closes #3518

What changes are included in this PR?

• Introduces a new tryZeroCopyConvert method in CometArrowConverters which receives ColumarBatch of any type and returns ColumnarBatch of CometVector objects if the input is composed of ArrowColumnVector objects, returns None otherwise.
• Columnar conversion path in CometSparkToColumnarExec always tries tryZeroCopyConvert first and falls back to current flow if zero-copy conversion is impossible.
• The implementation ignores batchSize configuration as it would be a lot more involved to do that with zero-copy... and I think zero-copy is more important in this case, especially if you assume that whatever operator produces the input will also have some similar configuration. Happy to change the implementation if you disagree though.

How are these changes tested?

• added tests that test conversion of hand-crafted ColumnarBatch objects as there's no out-of-box data source in spark that produces ColumnarBatch of ArrowColumnVector objects.

This turned out to be a bit complicated. arrow classes in common module are shaded, while objects coming from spark aren't, so we can't just pass underlying ValueVectors through. PR uses c data interface split across common and spark modules. spark batches are exported to plain pointers on spark module side (which isn't shading arrow) and imported into CometVector batches in common.
