GoogleServicesPlugin is not Configuration Avoidance compliant

[plastiv]

Describe the bug
GoogleServicesPlugin creates processDebugGoogleServices and processReleaseGoogleServices tasks eagerly by not using tasks.register().

To Reproduce

1. Apply plugin to any (android) project with plugins { id 'com.google.gms.google-services' version '4.3.5' }
2. Run ./gradlew --scan
3. Check build scan -> Performance -> Configuration
4. Total tasks created immediately is equal to 2 and it's processDebugGoogleServices and processReleaseGoogleServices tasks

Expected behavior
Tasks are created during execution. GoogleServicesPlugin is Task Configuration Avoidance complaint. Migration steps and guideline is provided at the link.

Additional context
At the very least create needs to be replaced with register here https://github.com/google/play-services-plugins/blob/e40a3f6a7653f9f3b2b1421ca0a5d1cb8d62705c/google-services-plugin/src/main/groovy/com/google/gms/googleservices/GoogleServicesPlugin.groovy
