Provide a mechanism to create a Java 9+ module

### Description of the problem / feature request:

Java 11 is the current LTS version of Java, and comes with the java module system (also known as the JPMS) There should be a way for Bazel to correctly generate a `module-info` and use that.

Simply spamming a `Automatic-Module-Name` into the manifest isn't sufficient since other parts of the Java ecosystem (notably jlink, and possibly graalvm) need accurate module info.

### Feature requests: what underlying problem are you trying to solve with this feature?

I want to write modern java.

### What's the output of `bazel info release`?

3.4.1

Start by researching Bazel's Java build and packaging behavior alongside Java 9+ JPMS requirements. Define how Bazel should generate and use accurate module-info metadata, including compatibility with jlink and possibly GraalVM. Done means a supported mechanism exists for writing modern Java modules rather than only adding Automatic-Module-Name.
