Niels Lohmann d82ab21724 Make diff() account for member order in ordered_json objects

diff() compared source/target objects purely by key set, ignoring
relative member order. For ordered_json (insertion-ordered, vector-
backed object_t), two objects that differ only in member order are
unequal via operator==, but diff() never emitted any patch operation
to fix the order, so source.patch(diff(source, target)) == target
could fail to hold.

Fix by detecting when common keys appear in a different relative
order in source vs. target (or when a new key would need to land
somewhere other than the end), and in that case removing and
re-adding the affected keys in target's order, which relies on
patch()'s "add" op appending new keys at the end of an ordered_map.
For plain json (std::map-backed, always key-sorted iteration) this
is a no-op and the original minimal per-key diff path is unchanged.
