Objectbox plugin doesn't support Gradle Configuration cache #1020

Describe the bug
The ObjectBox plugin doesn't support the Gradle Configuration cache. In AS arctic fox, AGP 7+ supports Gradle configuration cache. While running if configuration cache enabled mode it gives below error

- Plugin 'io.objectbox': read system property 'sun.arch.data.model'
  See https://docs.gradle.org/7.0.2/userguide/configuration_cache.html#config_cache:requirements:undeclared_sys_prop_read
- Task `:app:objectboxPrepareBuild` of type `io.objectbox.gradle.PrepareTask`: cannot serialize object of type 'org.gradle.api.internal.project.DefaultProject', a subtype of 'org.gradle.api.Project', as these are not supported with the configuration cache.
  See https://docs.gradle.org/7.0.2/userguide/configuration_cache.html#config_cache:requirements:disallowed_types
- Task `:app:transformClassesWithObjectBoxAndroidTransformForProdNotEncryptedRelease` of type `com.android.build.gradle.internal.pipeline.TransformTask`: cannot serialize object of type 'org.gradle.api.internal.project.DefaultProject', a subtype of 'org.gradle.api.Project', as these are not supported with the configuration cache.
  See https://docs.gradle.org/7.0.2/userguide/configuration_cache.html#config_cache:requirements:disallowed_types

Basic info (please complete the following information):

• ObjectBox version (are you using the latest version?): 3.0.1
• Reproducibility: [e.g. occurred once only | occasionally without visible pattern | always]: always
• Device: [e.g. Galaxy S20]: While building the project with configuration cache enabled
• OS: [e.g. Android 10]: N/A

To Reproduce
Steps to reproduce the behaviour:

1. Use Android studio Arctic fox
2. Create a sample project using object box library
3. Go to build analyzer(this appears when a build has succeeded)
4. Optimize configuration steps
5. It will show that ObjectBox plugin is not compatible
6. Run Try Configuration cache in a build
7. Now in build logs, it will print the logs(as attached by me previously)

Expected behaviour
Although Configuration cache is experimental, but we can start working on the same
