Enable Starlark java_binary in bazel

RELNOTES[inc]: `java_binary` is now implemented in Starlark. The only visible change is that `java_binary` is now a macro, with the `_deploy.jar` target(s) created by a separate rule. This affects the results of `blaze query` and has a (small) memory regression for builds with very many `java_binary` targets.

Downstream tests:
An earlier build had one windows launcher related failure: https://buildkite.com/bazel/bazel-at-head-plus-downstream/builds/2786 which has now been fixed:
https://buildkite.com/bazel/bazel-at-head-plus-downstream/builds/2791
(but other unrelated changes in the meantime have broken many more projects)
