The read thread could call Reset, which in turn tried to join the read
thread, leading to a SIGABRT. This manifested as Dolphin consistently
crashing when disconnecting a GC adapter and having a chance of crashing
a few seconds after connecting a GC adapter.

Force NetPlay Clients to Host Hardcore Status

ControllerInterface/SDL: Disable SDL's Windows.Gaming.Input controller handling.

ProcessorInterface: sync GPU just before PI_FIFO_RESET

If the host is in hardcore mode, all joining players will be set to hardcore mode; if not, all joining players will be set to softcore. This ensures all players have the same settings and remain synchroized.

Add Approved Patches - Eternal Darkness, Monster Hunter Tri

The primary focus of this PR is the Eternal Darkness patch which fixes hanging at startup, which prior to this fix makes Eternal Darkness unplayable in hardcore. The MHTri patch was added as well simply because it could be.

GXAbortFrame() is problematic for Dolphin because it first writes
PI_FIFO_RESET (for which we discard our internal fifo), then disables CP
reads (for which we execute pending commands in the GP fifo in emulated
memory). I don't know whether there is a race condition on hardware, but
there is one for us. Avoid this by also doing a GPU sync here.
