JNI: Support appending DECIMAL128 into ColumnBuilder in terms of byte array

[sperlingxx]

This PR is to add new append method for HostColumnVector.ColumnBuilder. This newly-added method appendDecimal128 allows users to add binary data, which represents the unscaled value of BigDecimal, as cuDF Decimal128.
This PR serves as a prerequisite of NVIDIA/spark-rapids#4784.
