[roll] Roll fuchsia [kernel][phys] Consolidate libarch ZBI in phys code
This change migrates the ZBI content of libarch into phys code: namely
constants are moved to phys headers and ZBI booting logic is moved into
BootZbi. We also collapse the separate ZbiBoot() and ZbiBootRaw()
routines into a single protecred BootZbi::ZbiBoot() method. The reasons
for this were that
* the only users of this code was BootZbi and its subclass,
TrampolineBoot
* BootZbi in many ways already acts as a reference implementation of ZBI
loading logic, so it makes sense to act further as that for booting
itself
* An upcoming change to the arm64 ZBI booting protocol was made awkward
by the current library and routine splits.
