Fix #31852: Sequencer duplicate cant move strips on Y axis in a meta

Issue was caused by some stuff happenign in wm_operator_finish() which uses
to somehow restore changes made by transformation invoke function.

Solved by not calling translation operator directly from duplication operator
(which is in fact really tricky) and use macros instead. This macros calls
duplication operator which simply duplicates strip, and then calls translation
operator.
