Context: #9651 PR #9651 demonstrated that it was fairly straightforward to use JDK-21 on CI. We don't want to fully bump to JDK-21, because we still support building with JDK-17, so we *at minimum* need to run tests on both JDK-17 and JDK-21. As a "minimal introductory step", add support for JDK-21: * Update to Gradle 8.12, for harmony with dotnet/java-interop. * Update the `<Javac/>` task to use `javac --release N` when using JDK-17 and later. JDK-11 doesn't support `javac --release`. (Why care about JDK-11? Because .NET 8 still supports it, and this will make future cherry-picking easier.) * Set `$(LatestSupportedJavaVersion)`=21.0.99, which removes the XA0030 error which would result from using JDK-21.
