Add ppc types to minidump_format.h (#25). r=waylonis

Browse source 
- New MDRawContextPPC struct, based on ppc_thread_state and others in
   mach/ppc/_types.h.
 - Add (defining where necessary) MDCPUArchitecture and MDOSPlatform enums
   to support non-x86/win dumps.  Add MD_CONTEXT_* definitions for non-x86
   CPUs.
 - Document a few more fields.
