[headers] Create gfxalloc.h, map.h, move protos to gfx.h, z64{player,view}.h (#2233)
* [headers] Create gfxalloc.h, map.h, move protos to z64{actor,player,view}.h

* oops

* bss

* comment on player_lib protos & format

* format map.h

* Move SCREEN_{WIDTH,HEIGHT} and SET_FULLSCREEN_VIEWPORT to z64view.h

* bss

* revert move screen_width/height

* bss
