GH-38354: [MATLAB] Implement fromMATLAB method for arrow.array.ListArray

[sgilmore10]

Rationale for this change

We should implement a static fromMATLAB method for arrow.array.ListArray that takes in a MATLAB cell array and returns an instance of arrow.array.ListArray. Adding this method enables users to create an arrow.array.ListArray by passing a MATLAB cell array to the arrow.array gateway function:

>> C = {[1 2 3], [4 5], 6};
>> array = arrow.array(C)

array = 

  ListArray with 3 elements and 0 null values:

    [
        [
            1,
            2,
            3
        ],
        [
            4,
            5
        ],
        [
            6
        ]
    ]

Internally, the arrow.array gateway function will call arrow.array.ListArray.fromMATLAB to construct a ListArray from the given cell array.

What changes are included in this PR?

1. Implemented fromMATLAB method on arrow.array.ListArray. This method accepts a MATLAB cell array and returns an instance of arrow.array.ListArray.
2. Set the ArrayStaticConstructor property of arrow.type.traits.ListTraits to @arrow.array.ListArray.fromMATLAB.
3. Added a switch case for "cell" to the arrow.array gateway function that invokes arrow.array.ListArray.fromMATLAB with the input cell array.

Are these changes tested?

Yes. I added a new test class to the test/arrow/array/list folder named tFromMATLAB.m.

Are there any user-facing changes?

Yes. Users can now create instances of arrow.array.ListArray by passing cell arrays to arrow.array:

>> C = {["A" "B"], ["C" "D" "E"], missing, ["F" "G"], string.empty(0, 1)};
>> array = arrow.array(C)

array = 

  ListArray with 5 elements and 1 null value:

    [
        [
            "A",
            "B"
        ],
        [
            "C",
            "D",
            "E"
        ],
        null,
        [
            "F",
            "G"
        ],
        []
    ]

Looks great! It's really nice to see support for nested cell arrays being added to arrow.array!
