Allow "reinterpretation" of framebuffer/zeta formats (#418)
* (Re)Implement format reinterpretation, other changes

* Implement writeback to guest memory, some refactoring

* More refactoring, implement reinterpretation the old way again

* Clean up

* Some fixes on M2MF (old Dma engine), added partial support for P2MF, fix conditional ssy, add Z24S8 zeta format, other fixes

* nit: Formatting

* Address PR feedback
