[FEATURE REQUEST] "Apply to all" when many name conflicts arise

[jesmrec]

Comes from #3935

Report: #4062 (comment)

When several conflicts happen at the time during a bulk copy or move operation, dialog should display a checkbox to give users the choice to apply the solution to all the subsequent conflicts, instead of fixing one by one.

oCIS dialog:

Web	iOS

That dialog appears in the first dialog. In checkbox is not clicked, every conflict will be fixed separately. If checked, the clicked solution will apply to all.
