Database: add a same_source_target_crs column to supersession table
This is in preparation for EPSG 9.8.11 import that supersedes a number of
grid transformation for US transformations, but the superseded and replacement
transformations don't operate on the same (source_crs, target_crs), which is
a bit weird. So in that situation, ignores the supersession.
