[otel-arrow-rust] Adaptive array builders for encoding

[albertlockett]

When encoding OTAP batches, we often need to dynamically switch between the array not being present in the record batch, or the array being present but with either arrow type dictionary (with variable key size depending on the cardinality), or the native array type.

For more information see here: https://arrow.apache.org/blog/2023/06/26/our-journey-at-f5-with-apache-arrow-part-2/

We already have this implemented in Go:
https://github.com/open-telemetry/otel-arrow/blob/main/go/pkg/otel/common/schema/builder/record.go

We should add the same functionality to otel-arrow-rust
