Subject: include: make the memory_object_t types translation functions mutable

Make the intran, outtran and destructor functions mutable using
preprocessor macros.  Make it possible to inject imports using the
MEMORY_OBJECT_IMPORTS macro.  This way, userspace servers can provide
their own translation functions.

* include/mach/mach_types.defs (memory_object_t): Make the translation
mutable using preprocessor macros.
* include/mach/memory_object.defs: Likewise for the inlined type declarations.
Honor MEMORY_OBJECT_IMPORTS.
* include/mach/memory_object_default.defs: Likewise.
