Reorganize library code into `libs/` (#3119)

* Reorganize files into libs/{dolphin,JSystem,PowerPC_EABI_Support,revolution,TRK_MINNOW_DOLPHIN}

* Update configure.py and project.py for new libs structure

* Refactor `#include <dolphin/x.h>` -> `<x.h>`

* Remove `__REVOLUTION_SDK__` forwards from dolphin

* Fix dolphin/ references in revolution

* Wrap `#include <dolphin.h>` in `!__REVOLUTION_SDK__`

* Always build TRK against dolphin headers

* Resolve revolution SDK header resolution issues
