Workaround `SERVICE_STOP` macro definition on WIN32.

One of the [GCP proto files](https://github.com/googleapis/googleapis/blob/master/google/cloud/securitycenter/v1/mitre_attack.proto#L186) recently introduce a message enum field named `SERVICE_STOP`.  Unfortunately this clashes with a macro from `winsvc.h`, so add `SERVICE_STOP` to the push/undef/pop wrappers.
