Move the JS java tests to be a proper java_test target.

Previously, we had a `sh_test` wrapping the `java_test` to do some setup.
This was extremely brittle on Windows, and relied on getting a deploy
jar from `java_test`. This breaks when updating to Bazel 7, where the
ability to get a deploy jar from `java_test` was removed.
Therefore, we now do all the test setup in `AllTests.java` instead.
This is much cleaner, and shouldn't break as easily.
