Blazor QuickGrid - Add class based on row item context property value

### Is there an existing issue for this?

### Is your feature request related to a problem? Please describe the problem.

I need to add class to a row cell based on its value. Something like:
```
@inject DataSource Data

@code {
string GetClass(DateOnly birthDate) => birthDate.Year < 2000 ? "table-success" : "table-warning";
}
```
The item context property is not accessible within Class property of PropertyColumn.

I tried to use TemplateColumn, but it only works for the tag within the cell and not the entire cell itself.
```

```
This also means that I have to manually handle sorting for the column which was automatically available through PropertyColumn tag.

### Describe the solution you'd like

There should be a CellClassFunc property in PropertyColumn which accepts a function with ItemModel as a parameter and string as return value.
The row item context should be accessible for that property.
