Sets "regions" variable for later use in FormHelper.

This variable is used to properly fill inputs in the "Theme Region"
section of the add/edit form.

@param null|\Block\Model\Entity\Block $block If a block entity is provided it
will be used to guess which regions has been already selected in each theme,
so we can properly show the selectbox in the form with the corrects
options selected.
@return void
