s4:rpc_server/lsa: let LookupSids* behave like Windows 2022/2025

The important part is the INVALID_SID should not
cause an early exit of the loop.

We need to return the intact names array with the
correct count. And only return INVALID_SID
if we would otherwise return NONE_MAPPED.

For SOME_NOT_MAPPED we need to ignore invalid sids
and just pretend they are not mapped.
