Patch Review

Defines `PageTableLevel`, `AperturePte`/`AperturePde`, `MmuVersion`, and `VaLevelIndex` trait. Clean foundational types.

**Minor:** The `_ => Self::VideoMemory` fallback in `AperturePte::from(Bounded<u64, 2>)` is unreachable since `Bounded<u64, 2>` covers values 0-3 which are all matched. An `unreachable!()` would be clearer.
