Goal: Allow Font family, font size, and font attributes to reference Static/Dynamic resources.

Currently, these attributes are parsed from the Width="string" and require the font attributes to be coded within the string. This makes keeping these coordinated with the ItemTemplate for the column a manual effort.

Determine if we can define a markup syntax that allows these to be declared as a individual BindableProperty
or a single 'Font' property to support the values.

Possible example using bindable properties.
...

<ColumnDefinintion.Width Text="@255"
FontFamily="{StaticResource LabelFont}"
FontSize="{StaticResource LabelSize}"
HorizontalAlignment="Start"
/>

Possible example using a ColumnWidth.Font property:

---

Finally, since ColumnWidth is itself a BindableProperty, can we define derived ColumnWidth class to support
Literal and CharacterCount column widths

Test SampleApp and Grid on Android, iOS, MacCatalyst.

The current sample has only been tested on Windows.

Define a column that contains variable text in the range of 0...255 and use @255 for the column width declaration.
When using the Width returned by TextUtilities.Measure(text, font family, font size), the resulting width causes the label
in the same column to wrap when displaying the text '255'.
If LineBreakMode = NoWrap, the text is clipped in the label.

The current workaround is at the end of the ColumnWidth(string literal, string fontFamily, double fontSize, FontAttributes attributes) constructor where it appends '4' to width. This is not viable for different font sizes and an alternative is needed.

Consider a test that uses Label.Measure versus TextUtiltiies.Measure for different text and font metrics to determine the variance across platforms.
