Subject: [PATCH] Correct the accept flag of the event object on DragMove

Summary:
  - `m_enabled` or `m_temporaryInhibition` could change while DragMove, so we should place `setAccepted()` on top of the function body. Otherwise, the accept flag of `event` could be wrong in the case `m_enabled` or `m_temporaryInhibition` changes while DragMove.
  - Don't call `setAccepted(false)` wrongly if `event->pos() == m_oldDragMovePo`

BUG: 396011

Test Plan:
- Drag a file from Dolphin -> Desktop (Desktop containment layout) -> too difficult -> fixed
- Drag an icon on Desktop (Folder view layout) from one place to another one -> too difficult -> fixed
- Add widgets to the Plasma panel -> too difficult -> fixed
- Drag a file from Dolphin -> Desktop (Folder view layout) -> still easy
