Add support for custom commands to set flags on themselves

This works for Python commands defined via a class (implement get_flags on your class) and C++ plugin commands (which can call SBCommand::GetFlags()/SetFlags())

Flags allow features such as not letting the command run if there's no target, or if the process is not stopped, ...
Commands could always check for these things themselves, but having these accessible via flags makes custom commands more consistent with built-in ones
