[macOS, compat] Allow games to boot in MacOS (#372)

This fixes the crashes on game launch caused by MacOS not being present in host_manager.cpp and enables primitiveRestart for MoltenVK to suppress a bunch of errors given in the log about  MoltenVK requiring primitiveRestart. Fixes an crash when switching kingdoms in Mario Odyssey as well

EDS is forced to 0, otherwise games do not show graphics

Note: For now only dynarmicc is working, performance will be slow
