tdf#57423 drawinglayer: PDF/UA export: more Alt texts for SdrObjects
Currently /Alt texts are generated from ObjectInfoPrimitive2D, but this
is only evaluated in VclMetafileProcessor2D::processGraphicPrimitive2D()
so while it's created for every SdrObject, it's ignored in most cases.
There doesn't appear to be a reason why this is done in
processGraphicPrimitive2D() and not a more generic location, the special
conditions that are checked there don't have anything to do with Alt
texts, they effectively guard some optimisation done to bitmaps in
PageSyncData::PlaySyncPageAct().
There is another issue in that not every SdrObject gets a
StructureTagPrimitive2D, and even if there is a StructureTagPrimitive2D
it may be ignored if it's in the background.
The Alt text must only be produced if there is a structure element for
the same SdrObject, else it would end up on some unrelated structure
element.
Fix all this by moving processing to a new function which checks that
there is a current StructureTagPrimitive2D for a SdrObject in effect.
The only problem with this is that previously Writer images produced Alt
text, and now they don't - but Writer needs some fixing anyway.
