ARROW-16983: [Go][Parquet] fix EstimatedDataEncodedSize of DeltaByteArrayEncoder (#13522)

`DeltaByteArrayEncoder` extends `encoder` which calculates `EstimatedDataEncodedSize()` by calling `Len()` on its `sink`. `DeltaByteArrayEncoder` however does not write its data out to sink, instead writing out to `prefixEncoder` and `suffixEncoder`, causing EstimatedDataEncodedSize to always return zero, resulting in `FlushCurrentPage` never being called.
