RFR: 8316669: ImmutableOopMapSet destructor not called [v2]

[Thomas Schatzl]

> Hi all,
> 
>   please review this addition to call the destructor of `ImmutableOopMapSet` before its memory is deleted. There is no functional problem as the destructor is empty, but it is surprising to free new'ed objects without calling its destructor.

> Testing: gha

> Thanks,
