delay importing all drawing elements until content is loaded, fdo#60488

Otherwise charts with data ranges on other sheets will not be painted
correctly as the data is missing when the chart is rendered for the
first time. This was not a problem before the cached value import
because the hard recalc would have forced a repaint anyway.

The new way should also be a bit quicker.
