Improvements to align CTS and Spec for Adapter.
- Add missing error condition to urAdapterGet which is mentioned in its description. - Return UR_RESULT_ERROR_INVALID_SIZE when NumEntries == 0 and phAdapters != NULL. - Check adapter reference count is updated accordingly after calls to urAdapterRetain/Release. - Update urAdapterGetInfo tests - ReferenceCountNotZero to check adapter reference count is not 0. - ValidAdapterBackend to check UR_ADAPTER_INFO_BACKEND returns a value enumerated in ur_adapter_backend_t.
