Subject: Separate guest/host tracking + unaligned protection (#6486)

* WIP: Separate guest/host tracking + unaligned protection

Allow memory manager to define support for single byte guest tracking

* Formatting

* Improve docs

* Properly handle cases where the address space bits are too low

* Address feedback
