fix: RNGP autolink not properly filter out pure C++ TurboModules (#46381)

Summary:
Hey.

The react-native gradle plugin didn't properly filter out [Pure](https://github.com/react-native-community/cli/pull/2387) C++ TurboModules for autolinking, which caused build failures as a non-existing gradle dependency would be emitted.

This makes Pure C++ TurboModules work again for Android.
