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
