This reverts commit ac35c7d8.

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

REFAC: return an empty projection in GetGCPProjection if the image has no gcp instead of asserting that the image has gcps (or segfault in release mode). This means that the user of ImageCommon does not have to check that the image has gcp before calling this method

When using ToJSON attribute to export metadata, the order the metadata
are exported depends on the platform. This is not a problem when
working with metadata, but the test (as they are currently made) need
a constant order of the metadata in the output file.

ENH: move implementation of non virtual methods to a source file to add them in the shared library in MetadataStorageInterface and MetadataSupplierInterface

BUG: remove cast to char* const& as it does not compile on windows, the lexical cast to char* is notneeded anyway

ReadXMLToList from GDAL is not part of the public API. It can be used
when compiling libgdal without --with-hide-internal-symbols
switch. But libgdal from Debian and Ubuntu packages doesn't contains
the symbols. The adopted solution is to implement a ReadXMLToList
function for the OTB.
