[filament/admin] Add ability to specify widgets' column span individually

[detygon]

It would be great to be able to specify widgets column span individually like filament/forms. This is expecially useful for ChartWidget`s.

You can do this by adding col-span-x to the outer element of your widget view :)

Thanks for your quick answer, actually I was using the provided template so I was not able to customize the view.
