Feature request #19571
Add support to read WFS GML data containing geometry collections

During interoperability tests between QGIS and the OGC-compliant (WFS 1.0, 1.1 and 2.0) LuciadFusion WFS server from Hexagon, it was noted that QGIS did not load WFS feature types containing a MultiGeometry GML element in the GetFeature response. QGIS doesn't detect the geometry. An example of such a feature type is available here:
An analysis in #19505-13 confirmed that this is currently not supported by QGIS.
[WFS client] Fix GetFeature BBOX in WFS 1.1 when the GetCapabilies CRS is urn:ogc:def:crs:OGC:1.3:CRS84 (refs #19571)
[WFS client] Try to handle layers of type GeometryCollection if the first GeometryCollection is made of geometries of the same type (fixes #19571)

- Subject changed from Add support to read WFS GML data containing MultiGeometry elements to Add support to read WFS GML data containing geometry collections
I changed the title because the problem is not MULTI geometries (that are perfectly supported in QGIS), but GEOMETRY COLLECTIONS.
Also this is not a WFS client thing only, but a QGIS thing in general.

Also there is a GDAL fix needed to parse the MultiGeometry.geometryMembers syntax returned in the WFS 1.1.0 GetFeature response:
