MMIO, which simplifies the stage 1 page table mappings needed by the
guest, and makes room for the pVM firmware allocation to be expanded.

This change consolidates some of the spread out information about
what ChromeOS developers need to know about crosvms differences to
other ChromeOS projects.
I created a new directory since I would expect a similar guide for
AOSP eventually.
This also adds more documentation on some of the process changes
suggested in go/crosvm-merge-improvements to improve the
stability of the merge process.
