Describe the enhancement requested

We should add benchmarks to be sure not to cause regressions while working on additional implementations of RecordBatch::ToTensor and Table::ToTensor.

The first step is to create a benchmark file with a basic benchmark for a simple uniform case of RecordBatch to Tensor conversion (all fields same type, no missing values). With follow-up features being added we should also add more cases to this benchmark file.
