### Rationale for this change
This change makes it possible to create an `arrow.tabular.Table` instance
from a list of `arrow.tabular.RecordBatch` instances whose `Schema`s are
consistent.
### What changes are included in this PR?
Added a new static method called `fromRecordBatches` to the MATLAB class
`arrow.tabular.Table`. This method should construct an `arrow.tabular.Table`
from a variable number of `arrow.tabular.RecordBatch`es.
**Usage Example**
```matlab
>> rb1 = arrow.recordBatch(table([1:5]', [6:10]'));
>> rb2 = arrow.recordBatch(table([11:15]', [16:20]'));
>> table = arrow.tabular.Table.fromRecordBatches(rb1, rb2)
table =
Arrow Table with 10 rows and 2 columns:
Schema:
Var1: Float64 | Var2: Float64
First Row:
1 | 6
```
### Are these changes tested?
Yes. Added four new test cases to the MATLAB test class `tTable`:
1. `FromRecordBatchesZeroInputsError`
2. `FromRecordBatchesOneInput`
3. `FromRecordBatchesMultipleInputs`
4. `FromRecordBatchesInconsistentSchemaError`
### Are there any user-facing changes?
Yes. Users can now create an `arrow.tabular.Table` instance via the static
method `fromRecordBatches`.
