Enable as many "supports" attributes as make sense for styling a field / virtual field

[bobbingwide]

The Field block's "supports" section is currently

"html": false,
"className": false

Requirements

It should be possible to support:

• font size
• font weight
• colours
• alignment
• etc It would be nice if we could also style the label, when the showLabel toggle is on.

Specific requirement

For the oik-events plugin it would be nice to be able to style the following 3 (virtual) fields to appear similar to the calendar date format that's used in some events calendar plugins.

• event_mon eg Jan-Dec
• event_day eg Mon-Sun
• event_dd eg 1-31
