GH-40059: [C++][Python] Basic conversion of RecordBatch to Arrow Tensor (#40064)

### Rationale for this change

There is no method currently in Arrow C++ to convert `Table` or `RecordBatch` to a `Tensor`. In https://github.com/apache/arrow/issues/40058 we are proposing to add the conversion and this PR starts with the basic implementation for `RecordBatch`.

### What changes are included in this PR?

Basic conversion `RecordBatch` → `Tensor` is added together with Python bindings. The implementation details are:

- One data type (all columns having for example an `int32` data type) support.
- No missing values support (only `NaN`).
- Column-major layout of the resulting `Tensor`.

### Are these changes tested?

Yes.

### Are there any user-facing changes?

No.
* Closes: #40059
