Optimize the page table implementation using the frame metadata
...
This PR also refactored the page table cursor, distinguishing `Cursor` from `CursorMut`, and split
a lot of functions to reduce dynamic condition checking.
There are also other sanitizations performed, including refactoring PTE's `is_huge` API to `is_last`,
hardening tracked mapping checks, and making `VmFrame` any size.

Use metadata to track VmFrames
...
In this commit, the frame metadata storage schema is implemented. The bootstrap process is refactored
and a boot page table is introduced to perform early stage metadata mapping. The metadata is then used
to track `VmFrame`s instead of the former `Arc` approach.
