Rollup merge of #119029 - dylni:avoid-closing-invalid-handles, r=ChrisDenton

Avoid closing invalid handles

Documentation for [`HandleOrInvalid`] has this note:

> If holds a handle other than `INVALID_HANDLE_VALUE`, it will close the handle on drop.

Documentation for [`HandleOrNull`] has this note:

> If this holds a non-null handle, it will close the handle on drop.

Currently, both will call `CloseHandle` on their invalid handles as a result of using `OwnedHandle` internally, contradicting the above paragraphs. This PR adds destructors that match the documentation.
