GH-37572: [MATLAB] Add `arrow.array.Date64Array` class (#37581)

### Rationale for this change

Now that `arrow.type.Date64Type` class has been added to the MATLAB Interface (#37578), we can add the `arrow.array.Date64Array` class.

`Date64Array`s can be created from MATLAB [`datetime`](https://www.mathworks.com/help/matlab/ref/datetime.html) values. 

### What changes are included in this PR?

1. Added a new `arrow.array.Date64Array` class.
2. Added a new `arrow.type.traits.Date64Traits` class.
3. Added `arrow.type.Date64Type` support to `arrow.type.traits.traits` function.
4. Factored out `convertToEpochTime` method on `TimestampArray` into internal helper function `arrow.array.internal.temporal.convertDatetimeToEpochTime`.
5. Updated `arrow.internal.test.tabular.createAllSupportedArrayTypes` to include `Date64Array`.

`Date64Array`s can be created from MATLAB [`datetime`](https://www.mathworks.com/help/matlab/ref/datetime.html) values using the `fromMATLAB` method. `Date64Array`s can be converted to MATLAB `datetime` values using the `toMATLAB` method.

**Example**
```matlab
>> dates = datetime + milliseconds(1:5)'

dates = 

  5×1 datetime array

   05-Sep-2023 16:47:12
   05-Sep-2023 16:47:12
   05-Sep-2023 16:47:12
   05-Sep-2023 16:47:12
   05-Sep-2023 16:47:12

% "SSS" displays fractional seconds (i.e. milliseconds)
>> dates.Format = "MMM dd, yyyy HH:mm:ss SSS"

dates = 

  5×1 datetime array

>> array = arrow.array.Date64Array.fromMATLAB(dates)

array =

]

>> array.toMATLAB

ans = 

  5×1 datetime array

% Milliseconds are preserved on round-trip
>> ans.Format = "MMM dd, yyyy HH:mm:ss SSS"

ans = 

  5×1 datetime array

### Are these changes tested?

1. Added a new `tDate64Array` test class.
2. Added `Date64` related test to `ttraits.m`.
3. Added a new `tDate64Traits.m` test class.

### Are there any user-facing changes?

Yes.

1. Users can now create `arrow.array.Date64Array`s  from MATLAB `datetime`s.

### Future Directions

1. Add round-trip precision tests for `TimestampArray` (i.e. similar to the test case `TestInt64MaxMilliseconds`).
2. Add a way to extract the raw `int64` values from an `arrow.array.Date64Array` without converting to a MATLAB `datetime` using `toMATLAB`.
