This patch changes KillHard() such that the IPC channel is immediately shut down with an error after a KillHard() is performed. This is done by fixing the previously-broken CLOSE_CHANNEL_WITH_ERROR support in ShutDownProcess, and calling that method after KillHard(). This ensures that after the process has been killed, no further messages will be delivered and processed, even if they were sent before the process was killed. In addition, the assertions and KillHard calls which are disabled for fuzzing were changed to also shut down the channel, making fuzzing IPC errors cause the connection to be terminated like it is in production for these actors. This change does not impact actors which ignore processing errors. Differential Revision: https://phabricator.services.mozilla.com/D178383
