[Charts] Support BarChart with scaleType: time

[alexfauquette]

The mains reason why BarPlot needs a band scale is the notion of bandWidth which is unique to this scale.

From what I understand, the main benefit of your proposal would be to have a nice formatting out of the box, instead of having to define formater as follow

valueFormatter: (date, context) =>
	context.location === 'tick'
              ? date.toLocaleTimeString(/* option to only display hours */)
              : `date.toLocaleString(/* option for the entire timestamp */)`,

Do I miss other nice feature it would bring?

Not quite exactly, it's not uncommon to represent time series with bars, or stacked bars. Especially when the data points are evenly spaced. Yet, the way I understand, the X-axis for a time series gets formatted differently than just formatting tick marks:

Here there is for instance the "...11PM Sat 23 01AM..." and it looks like it also adapts the amount of ticks to the available space. Basically, I'd like a variant on line/area chart but where the line is represented by bars.
