[roll] Roll fuchsia [libc] Add GuardedPageBlock class in new internal vmar.h

This adds a new header of internal Zircon-specific libc code.
The GuardedPageBlock class is the first building block that will
be used in the forthcoming implementation of allocating stacks et
al for both thread creation and process startup.  This code is
not yet load-bearing, but has its own unit tests.
