Rollup merge of #73930 - a1phyr:feature_const_option, r=dtolnay

Make some Option methods const

Tracking issue: #67441

Constantify the following methods of `Option`:
- `as_ref`
- `is_some`
- `is_none`
- `iter` (not sure about this one, but it is possible, and will be useful when const traits are a thing)
