Exhaustiveness: Reveal empty opaques in depth

Follow-up to https://github.com/rust-lang/rust/pull/116821. As noted [there](https://github.com/rust-lang/rust/pull/116821#discussion_r1376673420), the current implementation doesn't detect emptiness of opaques when the opaque is nested inside a type. This doesn't matter for stable behavior (which ignores nested empty types anyway) but does matter for the [`exhaustive_patterns`](https://github.com/rust-lang/rust/issues/51085)/[`min_exhaustive_patterns`](https://github.com/rust-lang/rust/pull/118803) features.

This PR fixes this behavior by adding `InhabitedPredicate::apply_reveal_opaque` that considers opaque types when determining inhabitedness.
