Subject: ipc: Create AttachmentBrokerPrivileged and
 AttachmentBrokerUnprivileged.

This CL is a refactor and contains no behavior changes.

AttachmentBroker is an abstract base class. I made two new abstract subclasses,
AttachmentBrokerPrivileged and AttachmentBrokerUnprivileged for use in
privileged and unprivileged processes respectively. These in turn are inherited
by AttachmentBrokerPrivilegedWin and AttachmentBrokerUnprivilegedWin.
