Description
* Replace `org.apache.kafka.common.test.TestUtils` with
`org.apache.kafka.test.TestUtils` in outer package modules to
standardize test utility usage
* Move `waitUntilLeaderIsElectedOrChangedWithAdmin` method from
`org.apache.kafka.test.TestUtils` to `ClusterInstance` and refactor for
better code organization
* Add `org.apache.kafka.test.TestUtils` dependency to
`transaction-coordinator` import control

This patch reorganizes our test infrastructure into three Gradle modules:
":test-common:test-common-internal-api" is now a minimal dependency which exposes interfaces and annotations only. It has one project dependency on server-common to expose commonly used data classes (MetadataVersion, Feature, etc). Since this pulls in server-common, this module is Java 17+. It cannot be used by ":clients" or other Java 11 modules.
":test-common:test-common-util" includes the auto-quarantined JUnit extension. The @Flaky annotation has been moved here. Since this module has no project dependencies, we can add it to the Java 11 list so that ":clients" and others can utilize the @Flaky annotation
":test-common:test-common-runtime" now includes all of the test infrastructure code (TestKitNodes, etc). This module carries heavy dependencies (core, etc) and so it should not normally be included as a compile-time dependency.
In addition to this reorganization, this patch leverages JUnit SPI service discovery so that modules can utilize the integration test framework without depending on ":core". This will allow us to start moving integration tests out of core and into the appropriate sub-module. This is done by adding ":test-common:test-common-runtime" as a testRuntimeOnly dependency rather than as a testImplementation dependency. A trivial example was added to QuorumControllerTest to illustrate this.
