[roll] Roll fuchsia [fake-object] Make fake objects "real" enough to use over channels

Previously, fake objects were implemented via hijacking unused handle
bits to allow for a quick static check if a handle was fake vs real.
Unfortunately, it meant those handles were not real handles for any
situation where a handle may be transferred over a channel. Handles are
now VMOs of size 0 with a propname set, and general logic for
maintaining the table has been simplified. To better fake objects over
channels, HandleTypes have been replaced with zx_obj_type_t types that
match what the syscalls use. Care has also been taken to ensure that any
uses of zx_channel_*_etc will manage the types on each side of the
syscalls when fake objects are involved.

Any derived fake-object (bti, msi, resource) can now be passed
over a FIDL protocol in unit tests as long as they remain in the same
process that is minting the fake objects.
