ArmVirtPkg: RMM 1.0-eac2 - Add RIPAS DESTROYED state

The RMM specification 1.0-eac2 updates the RIPAS state
to add a new DESTROYED state for an address which is
inaccessible to the Realm due to an action taken by
the Host.

Therefore, update the RSI RIPAS state enum to add the
new RIPAS_DESTROYED state.
