### Rationale for this change
Currently, the display for `arrow.tabular.RecordBatch` and
`arrow.tabular.Table` are not very MATLAB-like.
### What changes are included in this PR?
1. Updated the display of both `arrow.tabular.Table` and
`arrow.tabular.RecordBatch`.
2. Added a new utility function `arrow.internal.display.boldFontIfPossible`
3. Renamed `arrow.array.internal.display.pluralizeStringIfNeeded` to
`arrow.internal.display.pluralizeStringIfNeeded`
4. Renamed `arrow.tabular.internal.displaySchema` to
`arrow.tabular.internal.display.getSchemaString`.
**Example RecordBatch Display**
```matlab
>> t = table(1, false, datetime(2023, 1, 1), VariableNames=["Number",
"Logical", "Date"]);
>> rb = arrow.recordBatch(t)
rb =
Arrow RecordBatch with 1 row and 3 columns:
Schema:
Number: Float64 | Logical: Boolean | Date: Timestamp
First Row:
1 | false | 2023-01-01 00:00:00.000000
```
**Example Table Display**
```matlab
>> t = table(1, false, datetime(2023, 1, 1), VariableNames=["Number",
"Logical", "Date"]);
>> arrowTable = arrow.table(t)
arrowTable =
Arrow Table with 1 row and 3 columns:
Schema:
Number: Float64 | Logical: Boolean | Date: Timestamp
First Row:
1 | false | 2023-01-01 00:00:00.000000
```
### Are these changes tested?
Yes, I added a new test class in `matlab/test/arrow/tabular` called
`tTabularDisplay.m`.
### Are there any user-facing changes?
Yes. Users will now see the new `Table`/`RecordBatch` display
