Use NDIS 6.85 interfaces, if available

NDIS 6.85 was introduced in Server 2022, and the "NICStrictPropertyValidation"
test requires that drivers for Server 2022 declare support for NDIS 6.85.
Conditionally include the minimum NDIS 6.85 support, if available in the WDK,
in order to pass this test. No additional features of NDIS 6.85 have been
included.
NDIS_RUNTIME_VERSION_685 is only defined if the ndis.h header is from WDK 20384
or later, and NDIS685_MINIPORT is defined by the project.
