JVM_IR: move MoveOrCopyCompanionObjectFields down a bit

More specifically, it should be done *just before*
JvmPropertiesLowering, as walking the IR tree between them will result
in visiting the moved backing fields twice (once via the companion's
parent, once via the IrProperty).

Ideally, this group of 3 lowerings should be merged into 1 as they are
completely inseparable, but this is slightly harder to do properly.
