Make columnVisibility type safe

[nimo23]

The properties eligable for columnVisibility used within table are currently not type-safe:

state: {
	isFullScreen,
	columnVisibility: {
	'mrt-row-expand': isFullScreen,
	task: isFullScreen,
        anything: true // column anything does not exist within my columns-definition
}

Maybe it is possible to make it type safe by having an aggregation type from my column definition and the internal columns, so that anything: true is not allowed to be placed inside the columnVisibility.
