Kernel/SVC: Partially implemented svcReplyAndReceive.

It behaves mostly as WaitSynchronizationN with wait_all = false, except for IPC buffer translation.

The target thread of an IPC response will now wake up when responding.
IPC buffer translation is currently not implemented.
Error passing back to svcSendSyncRequest is currently not implemented.
