Kenneth Moreland 6d37ce9453 Remove invalid PortalType
Several ArrayHandles (actuall Storage implementations) had a fake portal
type that only defined invalid value types and no Get/Set methods. The
idea was to quickly identify when using a read-only array for writing.
However, this was more trouble than it was worth as the compiler just
gives  an incomprehensible error and it is hard to track down the actual
value.

Now actually define some type even if it is never used.
