ca37093fc2 GH-40062: [C++][Python] Conversion of Table to Arrow Tensor (#41870 )

### Rationale for this change

There is currently no method to convert Arrow Table to Arrow Tensor (conversion from columnar format to a contiguous block of memory). This work is a continuation of `RecordBatch::ToTensor` work, see https://github.com/apache/arrow/issues/40058.

### What changes are included in this PR?

This PR:
- implements `Table::ToTensor` conversion
- adds bindings to Python
- adds benchmarks in C++
- removes the code in `RecordBatch::ToTensor` and uses the Table implementation (`RecordBatch::ToTensor` benchmarks checked)

### Are these changes tested?

Yes, in C++ and Python.

### Are there any user-facing changes?

No, it is a new feature.
* GitHub Issue: #40062
