Port the toolbar popup to select the slide layout to use
from using two ValueSet widgets to using weld::IconView
instead.
This helps to be more consistent with other platform/toolkit
widgets and reduces custom widget logic.
Adjust indices used to account for the fact that
weld::IconView indices are 0-based while the ValueSet ones
are 1-based. For the particular case here, custom non-continguous
item IDs were used for the ValueSet items that
correspond to the AutoLayout enum values.
Store those custom IDs as the IDs of the weld::IconView items and
retrieve the ID again in LayoutToolbarMenu::IconViewItemActivatedHdl.
The popup can be triggered like this:
* start Impress
* in the toolbar, click on the "Slide Layout" button
