Rollup merge of #137808 - jswrenn:droppy-unsafe-fields, r=nnethercote
Do not require that unsafe fields lack drop glue

Instead, we adopt the position that introducing an `unsafe` field itself carries a safety invariant: that if you assign an invariant to that field weaker than what the field's destructor requires, you must ensure that field is in a droppable state in your destructor.
