Allow completely disabling Error Prone

### Description of the feature request:

Hi.

Back in https://github.com/bazelbuild/bazel/commit/58dc6b98f92c88bd788b6459a2e26101c99f245a, the `--extra_checks:off` flag that allowed completely disabling Error Prone was removed, in favor of the `-XepDisableAllChecks` flag, which runs EP but disables all checks.

I just ran into https://github.com/google/error-prone/issues/4656 when trying to upgrade to the Java 24 EA build, despite our build disabling EP via `-XepDisableAllChecks`.

I think it would be nice to be able to disable EP completely, so we wouldn't be affected by this type of issue in the future coming from a tool we don't use, especially since upgrading EP requires also upgrading Bazel.

Would it be possible to add an option to completely disable EP back to Bazel?

Start by tracing Bazel's Java Rules integration with Error Prone and reviewing commit 58dc6b98f92c88bd788b6459a2e26101c99f245a, which removed --extra_checks:off. Compare that behavior with -XepDisableAllChecks and the Java 24 failure described in Error Prone issue 4656. Done means Bazel can bypass Error Prone entirely without blocking Java upgrades, with coverage for the new option.
