build: Add an integrationTests task that runs every module's suites

The Spring Boot 2, 3 and 4 integration suites live in separate modules,
so they are separate tasks. integrationTests runs all of them, the
jakarta agent suite included, in one invocation. Each suite starts its
own servers on free ports, so Gradle runs them in parallel.

The suites aren't part of check; the Spring Boot matrices run them.
