Droiddoc Support in Soong

Support Droiddoc to Soong based on core/droiddoc.mk. The non-std doclet
based droiddoc compilation output is a "real" stubs.jar instead of a
directory of java files and a timestamp file.

The std doclet based javadoc compilation output is a "empty" stubs.jar
instead of a timestamp file.

The stubs.jar will be exported to
out/target/common/obj/JAVA_LIBRARIES/$(LOCAL_MODULE)_intermediates/classes.jar
and out/target/common/docs/$(LOCAL_MODULE)-stubs.jar

A $(LOCAL_MODULE).zip file will be generated also, and is exported to
out/target/common/docs/$(LOCAL_MODULE)-docs.zip if property: installable is not set
to false.

Bug: b/70351683
Test: unittest + convert libcore docs Android.mk to Soong manually.
