[roll] Roll fuchsia [kernel][arm64] Simplify vmm_page_fault_handler status translation

The purpose of this change is to improve code clarity.  No change in
behavior.

Refactor the status translation logic out of vmm_page_fault_handler
and into its own function.

Also, simplify the check in arm64 data abort and instruction abort
handlers to compare against ZX_OK.  vmm_page_fault_handler returns a
zx_status_t.  The is no reason for the value to be greater than zero.
This change makes the handlers consistent across all three
architectures.

This is a modified reland of 98baebea55c11d30a7a73fba70dc512a8e44194e.
