  If Seed is NULL, then default seed is used.
  If this interface is not supported, then return FALSE.

  @param[in]  Seed      Pointer to seed value.
                        If NULL, default seed is used.
  @param[in]  SeedSize  Size of seed value.
                        If Seed is NULL, this parameter is ignored.

  @retval TRUE   Pseudorandom number generator has enough entropy for random generation.
  @retval FALSE  Pseudorandom number generator does not have enough entropy for random generation.
  @retval FALSE  This interface is not supported.
