Add a way for the client apps to specify custom information in case of out-of-process

scenarios that the OOP server can use in whatever way it wants to.

Fix a bug in CrashGenerationserver where CreateNamedPipe failure was not checked correctly.

TODO in near future: Add a custom stream to minidump files for the custom information.
