Resets the signal on the given handle, ensuring future calls to [[#svcWaitSynchronization]] on this handle will sleep until the handle is signaled again. If the handle is a ReadableEvent, this is equivalent to calling svcClearEvent() on the handle.
If the handle is a Process, it will clear the signaled state (which is set when the process changes [[#ProcessState]]. Once the process enters the Exited state, calling svcResetSignal on the process will no longer have an effect (the process is permanently signaled), and the syscall will return 0xFA01.

If the process is attached, report the Break event. Then, if svcContinueDebugEvent didn't apply IgnoreException on the thread: if TPIDR_EL0 is 0, adjust ELR_EL1 to retry to svc instruction (and set TPIDR_EL0 to 1).
Otherwise, if bit31 in reason isn't set, perform crash reporting (see Exception Handling section below), if it doesn't terminate the process adjust ELR_EL1 as well.
Otherwise just return 0.
