Add version to JavaRuntimeInfo.

1. As suggested in bazelbuild#6354 (comment), add a JDK version attribute to the java_runtime rule. This will allow changing behavior based on the Java runtime's version.

2. As an application of the above, pass -Djava.security.manager=allow to Java tests on JDK 17+. This makes the Bazel Java test runner to work on JDK 19. Fixes bazelbuild#14502.

3. To make the above generally useful, the remote_java_repository and local_java_repository must set the new version attribute in the java_runtime rules that they create. This means the old static jdk.BUILD file no longer suffices. Move the contents of jdk.BUILD into a Starlark file, so the version can be interpolated in by JDK repository rules and macros. (This isn't the nicest, but local_java_repository is not a repository rule, so the template cannot be in a non-Starlark file.)

Closes bazelbuild#17775.
