Concern multiple geometries in same layer for geopackage

[signedav]

• Passing parameter gpkgMultiGeomPerTable
• Building layer url including geometry-column if the layer source is used multiple times (because of multiple geometries in a table)

This does only work with GDAL version >=3.8. Means depending on the QGIS Version. Windows Builds have it since quite a while (3.36) but Ubuntu from the current repositories not yet.

When a schema is created with this parameter gpkgMultiGeomPerTable it can neither create a project on QGIS with GDAL<3.8 nor read a project that has been created on a QGIS with GDAL<3.8

Solution:

• The setting for gpkgMultiGeomPerTable is only available for QGIS with GDAL>=3.8 See Multiple Geometries on Geopackage ili2db parameter QgisModelBaker#970
  
  Otherwise the setting is invisible and the parameter is false
• On creating a project it checks (a) gpkgMultiGeomPerTable and (b) GDAL>=3.8 and maybe (c) if there are in fact such tables with multiple geometries (because otherwise it doesn't care)
• Tests

Find current GDAL Version of Windows Builds
https://github.com/jef-n/OSGeo4W/tree/master/src/gdal/osgeo4w
Means we can check the QGIS version to decide if we do it or we dont...

Current Ubuntu Nightly still with 3.4 apparently. Depending on the repository there... maybe we can check the GDAL Version directly, but I don't know how at the moment. Something like:

  const QString gdalVersionCompiled { GDAL_RELEASE_NAME };
  const QString gdalVersionRunning { GDALVersionInfo( "RELEASE_NAME" ) };

but not sure how it's handled in QGIS Api.
