The RMM specification 1.0-eac2 updates the RSI_IPA_STATE_SET
interface to add a new parameter RsiRipasChangeFlags.
The RsiRipasChangeFlags fieldset is 64 bits and the bit 0
describes the RsiRipasChangeDestroyed type which is used
to indicate if a RIPAS change from DESTROYED should be
permitted or not.
Therefore, define the macros for specifying the
RsiRipasChangeFlags that represent the
RsiRipasChangeDestroyed type.
