GH-37570: [MATLAB] Implement `isequal` for the `arrow.tabular.RecordBatch` MATLAB class (#37627)



### Rationale for this change

Following on to https://github.com/apache/arrow/pull/37474, https://github.com/apache/arrow/pull/37446, and https://github.com/apache/arrow/pull/37525, we should implement `isequal` for the `arrow.tabular.RecordBatch` MATLAB class.

### What changes are included in this PR?

1. Implemented `isequal` method for `arrow.tabular.RecordBatch`

### Are these changes tested?

Yes. Added `isequal` unit tests to `tRecordBatch.m`.

### Are there any user-facing changes?

Yes, users can now use `isequal` to compare `arrow.tabular.RecordBatch`es. 

**Example**

```matlab
>> t1 = table(1, "A", false, VariableNames=["Number",  "String", "Logical"]);
>> t2 = table([1; 2], ["A"; "B"], [false; false], VariableNames=["Number",  "String", "Logical"]); 
>> rb1 = arrow.recordBatch(t1);
>> rb2 = arrow.recordBatch(t2);
>> rb3 = arrow.recordBatch(t1);

>> isequal(rb1, rb2)

ans =

  logical

   0

>> isequal(rb1, rb3)

ans =

  logical

   1
```

### Future Directions
1. #37628

* Closes: #37570
