Allow GetPhysicalRef to hold a past-the-end offset (#6141)

Browse source 
Games will sometimes use these when representing open right bounds
and so disallowing it caused regressions, with a notable example
being when MemoryFill is called to the end of vram, causing an
"invalid end address" error.
This had been noted on a comment in GetPhysicalRef prior to the
regression.
