Fix issue where the IPC server can fully consume a CPU core and prevent incoming connections

If the call to CreateNamedPipe fails here:

runtime/src/native/eventpipe/ds-ipc-pal-namedpipe.c

Lines 372 to 387 in af11dbc

	ipc->pipe = CreateNamedPipeA (
	ipc->pipe_name, // pipe name
	creationFlags,
	PIPE_TYPE_BYTE | PIPE_WAIT | PIPE_REJECT_REMOTE_CLIENTS, // message type pipe, message-read and blocking mode
	PIPE_UNLIMITED_INSTANCES, // max. instances
	out_buffer_size, // output buffer size
	in_buffer_size, // input buffer size
	0, // default client time-out
	NULL); // default security attribute
	DS_EXIT_BLOCKING_PAL_SECTION;
	if (ipc->pipe == INVALID_HANDLE_VALUE) {
	if (callback)
	callback ("Failed to create an instance of a named pipe.", GetLastError());
	ep_raise_error ();
	}

We will end up with an invalid handle for the pipe and the overlapped IO event. There currently is no code that tries to reset the connection and we will repeatedly try to poll an invalid handle, leading to one core being pegged as the wait fails due to an invalid handle and we keep waiting.

This PR makes it so we will call ds_ipc_listen when we run in to an error, which will reconnect to the named pipe. It also adds a delay when we detect an error, so if there are undetected cases that cause the same issue we will at least not consume the whole core we are running on.
