Fix package-split-across-modules issue in art.module.api.annotations.

This target builds dalvik.system.VersionCodes. Several dalvik.system
classes (DexFile and the various *ClassLoader classes) are in
java.base when sdk_version is core_current. The package is therefore
split across modules. This hasn't been a problem until now since
everything built with and sdk_version of core_current has implicitly
had a java_version of 1.8, but that needs to change (see
https://r.android.com/1145829).

This change explicitly opts this target into java_version 1.9, which
triggers the issue ahead of the Soong change, and then using
patch_module to fix the issue.
