fixes #23247; don't destroy openarray since it doesn't own the data (#23254)
fixes #23247
closes #23251 (which accounts for why the openarray type is lifted
because ops are lifted for openarray conversions)

related: https://github.com/nim-lang/Nim/pull/18713

It seems to me that openarray doesn't own the data, so it cannot destroy
itself. The same case should be applied to
https://github.com/nim-lang/Nim/issues/19435. It shouldn't be destroyed
even openarray can have a destructor. A cleanup will be followed for
https://github.com/nim-lang/Nim/pull/19723 if it makes sense.

According to https://github.com/nim-lang/Nim/pull/12073, it lifts
destructor for openarray when openarray is sunk into the function, when
means `sink openarray` owns the data and needs to destroy it. In other
cases, destructor shouldn't be lifted for `openarray` in the first place
and it shouldn't destroy the data if it doesn't own it.
