[SERVICES]

[SERVICES]
- Remove the reference counter from the common handle type as a handle is never shared or duplicated.
- Remove the access right from the service handle as it is not used.
- Dereference service manager handles and service handles in two separate functions that SEH-protect the initial access to the handle and signature check. This will protect SCM from bogus handles.
