Fix java_plugins to work with Android rules

[jongerrish]

java_plugin rules used from Android rules fail with the following error:-

ERROR: /Users/jgerrish/indiekid/rules_kotlin/examples/android/app/BUILD.bazel:29:15: in deps attribute of android_binary rule //app:app3: Dependencies on .jar artifacts are not allowed in Android binaries, please use a java_import to depend on kotlin_rules_maven/v1/https/maven-central.storage.googleapis.com/repos/central/data/com/google/auto/value/auto-value/1.6.5/auto-value-1.6.5.jar. If this is an implicit dependency then the rule that introduces it will need to be fixed to account for it correctly.. Since this rule was created by the macro 'android_binary', the error might have been caused by the macro implementation

This is due to including plugins as compile dependencies.

Remove plugins from compile dependencies and add a test to ensure annotation processed code is available when using Android rules.
