Split z64.h: move various things, state, sram, gfx, jpeg, prerender, speedmeter (#1487)
* Split z64.h more

* fix speedmeter.h (expect this kind of issue resolution to pop up eventually)

* fix z64object.h

* fix z64state.h

* fix (probably only partially) z64play.h

* fix fix speedmeter.h :)

* revert making a play header (sadge), add/split transition & transition_instances

* move stuff to cutscene, interface

* Move `TransitionCircle%` enums to `z64transition_instances.h`

* z64state.h -> z64game.h with a "this is not final" comment

* forward declare GraphicsContext in z64game.h instead of including the header file for it

* don't comment on where the forward declarations are from

reasoning:
1) it's easy to go out of sync (like this comment, it was outdated anyway)
2) any IDE can easily find the struct anyway
