pose_library: minor changes for shortcuts to show in menus

template_asset_view operators for the pose library now match the menu
items.

- Set 'flipped' to false for the activate operator.

- Remove 'release_confirmed' assignment for the drag operator,
  this is now set based on the event that activated it.

Part of fix for T103267.
