Add .proto files to extract_includes.bat
For google/or-tools, on windows, we need to use `import "google/protobuf/wrappers.proto";` since we want "optional" int64 and in version3 POD get default value...
-> so we use "google.protobuf.Int64Value" since 0 is a valid value and different from "not set" for our use case.
