Test Gradle plugin on relevant PRs (#2509)

* Update Gradle used in tooling subprojects

* Update Kotlin in Compose Gradle plugin

* Decrease verbosity of Gradle plugin tests

* Disable mac sign test

* Add workflow to test Gradle plugin

* Fix custom jdk tests on Linux

* Make Compose Gradle plugin build compatible with Configuration cache

* Print tests summary

* Remove unused code

* Refactor tests configuration

* Turn off parallel execution

* Try adding windows runner

* Turn off fail fast

* Fix Windows test issues

#2368

* Adjust default proguard rules

The following rule is needed to fix tests on Windows:
```
-dontwarn org.graalvm.compiler.core.aarch64.AArch64NodeMatchRules_MatchStatementSet*
```

Other rules are just to make builds less noisy.
Kotlin's `*.internal` packages often contain
bytecode, which triggers ProGuard's notes.
However, these notes are not actionable for
most users, so we can ignore notes by default.

#2393
