[SERVICES][ADVAPI32] Support the security process aka lsass.exe
- Reserve the pipe NtControlPipe0 for the security process.
- Count regular service control pipes from 1.
- Use I_ScIsSecurityProcess to identify the security process.
- Services.exe uses the SECURITY_SERVICES_STARTED event to notify the
security process that NtControlPipe0 is ready for use.
