Different way to determine if paragraph is within a list
pptx import seems little flaky in this regard, EE_PARA_OUTLLEVEL
isn't always set (no such problem with odp). Instead, we'll query
paragraph's depth and visibility of bullets/numbering

Enhance TaggedPDF export (accessibility)
The current tagged PDF export does not well support
quite some internal structures. This includes all
apps (Draw/Impress/Writer/Calc) and some areas.
Area AlternativeText ('/Alt'):
Only writer currently at least adds Title information,
but we also have Description (MS does add) and Name.
Target is to add this information when available to
content frames.
Writer did that by manually adding that tag using
PDFExtOutDevData::SetAlternateText, but only used
Title so far.
To make this work as broad as possible, better add
this to primitives. There is already a primitive called
ObjectInfoPrimitive2D that encapsulates any content
adding Name/Title/Description using GroupPrimitive
functionality.
Changed Writer to use that way. Draw/Impress already
uses it, all apps now use graphic paint using primitives,
so we have a natural target to encapsulate. Add support
to VclMetafileProcessor2D to interpret it and add
- if mpPDFExtOutDevData->GetIsExportTaggedPDF() - that
data using a combination of Name/Title/Description and
add using mpPDFExtOutDevData->SetAlternateText.
This works for Draw/Impress/Writer, but not for Calc
because Calc does not create more complex data structures,
so SetAlternateText does not work (see
PDFWriterImpl::setAlternateText for more infos).
Area Tagged ListContent (use 'L', 'LI', 'LBody' PDF tags):
To support this in Draw/Impress, we can also use a similar
way to support in primitives. For this I evaluated how to
add needed OutlineLevel information to the existing (and
already used to write 'P') TextHierarchyParagraphPrimitive2D.
Added this and now ready to use in VclMetafileProcessor2D
::processTextHierarchyParagraphPrimitive2D.
Added now using the OutlineLevel information at the
TextHierarchyParagraphPrimitive2D. Made sure there are
fallbacks to unchanged old behaviour when no PDF export
or no Tagged-PDF used. Creating now '/L', '/LI' and '/LBody'
statements as tagged PDF wants us to do.
Exported PDF still works well while additionally a verifier
as 'PAC 3' shows the expected and wanted structure.
This will work now for any text in Draw/Impress and for
Draw-Objects using Lists in Calc. Need to check for direct
text in Calc cells and Writer - and guess how big the
effort would be for these to make it work there, too.
Area '/Artifact':
Target is to avoid too much ScreenReader hassle when
Impress uses Pictures/FillPatterns etc. in Background
- what means on MasterPage in Impress.
Experimented with different possibilities. Decided to use
existing StructureTagPrimitive2D and extend for info if
encapsulated data is 'Background' data -> on MasterPage.
Can be created in ImplRenderPaintProc in method
createRedirectedPrimitive2DSeque as needed by checking
for MasterPage member (remember: primitives need to be
as independent from model data as possible, never include
e.g. a SdrObject reference in any way).
Tried different ways to use this in VclMetafileProcessor2D
processStructureTagPrimitive2D, see comments there. Current
best solution is to just *not* create StuctureTag information
for these objects.

tdf#87884: UnoControlTabPageModel is using tabs w/o WB_NOBORDER
No border attribute is a special case for vcl/TabControl, so by defualt
created with corresponding UNO interface tabs were invisible.
To create invisible tabs there is already "tabcontrolnotabs"(?)
