protected function GridStackLayout::interpolateItems in GridStack 8.2

Interpolate data from Layout Builder to match original construct.

We do this because we don't manually put regions into templates. Instead structured with nested grids, if any, to have one template for any known layout possibility: one or two dimensional layouts. With everything being cached at D8, this shouldn't make much different than hard-coded layouts at YML files which still need parsing anyway.
