Use metadata to track VmFrames

Browse Source 
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.
