BrowserSubProcess - Change SetProcessShutdownParameters priority to 0x200

- Change to 0x200 which is low end of 'Application reserved "in between" shutdown range.'
- Remove logging as it wasn't working, must be too early to use the LOG(INFO) CEF macro

Test with a GetProcessShutdownParameters in debugger shows working e.g.

if (SetProcessShutdownParameters(0x200, SHUTDOWN_NORETRY))
{
	DWORD level = 0;
	DWORD flags = 0;
	GetProcessShutdownParameters(&level, &flags);
}
