URL: https://github.com/apache/arrow-rs/pull/9963
# Rationale for this change
Adds a builder method that configures VariantArrayBuilder to produce a
shredded VariantArray at build() time.
# What changes are included in this PR?
Add shredding_schema: Option<DataType> field to VariantArrayBuilder
Add with_shredding(as_type: DataType) -> Self — rows are still appended
unshredded via append_variant; the shredding pass runs once at build() by
delegating to shred_variant
# Are these changes tested?
unit tests
# Are there any user-facing changes?
Yes, usage:
```
let arr = VariantArrayBuilder::new(3)
.with_shredding(DataType::Int64)
.tap(|b| { b.append_variant(Variant::Int64(42)); })
.build(); // returns shredded VariantArray
```
