Agent instrumentation prevents the use of Gradle's configuration cache

[wilkinsona]

Describe the bug
When the agent instruments a task, it breaks Gradle's configuration cache.

To Reproduce
Steps to reproduce the behavior:

plugins {
	id 'java'
	id 'org.graalvm.buildtools.native' version '0.9.13'
}

repositories {
	mavenCentral()
}

graalvmNative {
    toolchainDetection = false
}

$ gradle test --configuration-cache
Configuration cache is an incubating feature.
Calculating task graph as no configuration cache is available for tasks: test
[native-image-plugin] Instrumenting task with the native-image-agent: test

FAILURE: Build failed with an exception.

* What went wrong:
Configuration cache problems found in this build.

7 problems were found storing the configuration cache, 4 of which seem unique.
- Task `:test` of type `org.gradle.api.tasks.testing.Test`: 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/7.5.1/userguide/configuration_cache.html#config_cache:requirements:disallowed_types
- Task `:test` of type `org.gradle.api.tasks.testing.Test`: cannot serialize object of type 'org.gradle.api.internal.tasks.DefaultSourceSetContainer', a subtype of 'org.gradle.api.tasks.SourceSetContainer', as these are not supported with the configuration cache.

Expected behavior
Agent instrumentation does not prevent the use of Gradle features.

System Info (please complete the following information):

• OS: N/A
• GraalVM Version: N/A
• Java Version: N/A
• Plugin version: 0.9.13
• Gradle version: 7.5.1

Additional context
Disabling the agent does not help:

graalvmNative {
	agent {
		enabled = false
	}
	toolchainDetection = false
}

7 problems are still reported. However, configuring the predicate to avoid any instrumentation does help:

graalvmNative {
	agent {
		java.util.function.Predicate<Test> predicate = { t -> false }
		tasksToInstrumentPredicate = predicate
	}
	toolchainDetection = false
}

With this configuration in place, 0 problems are reported.
