The class XMLMetadataSupplier belongs to a public hierarchy,
it should not be possible to copy it.

Merge branch '2024-metadata-refac' of gitlab.orfeo-toolbox.org:orfeotoolbox/otb into 2024-metadata-refac

Changes in otbMetadataSupplierInterface: method
- GetRessourceFile now takes a parameter
- new method GetRessourceFiles

Add a new Fetch method for the Extra metadata. And
the other Fetch methods had an issue with fetching the
metadata for the bands.

REFAC: don't use GetProjectionRef in ChangeInformationImageFilter because the method don't use the itk metadata dictionary anymore

BUG: don't write identity geotransform (0,1,0,0,0,1) in ImageTest and VectorImageTest (back compatibility)

BUG: use SetProjectionRef() instead of MetadataKey::ProjectionRefKey to set the output projection (new metadata framework)
