docs: Start a comprehensive CPU architecture document
...
With docs/cpu.md, I aim to describe the CPU architecture as fully as
necessary to allow understanding it without having to look into emulator
source code anymore.
This currently leaves encoding.md a bit stranded, because I didn't quire
know how to integrate it into this new document.
