Generate java_api_library from java_sdk_library

This change enables java_sdk_library to generate java_api_library
modules per api surface, so that from-text stubs can be generated per
api domain scope. This module is only created when
`--build-from-text-stub` flag is passed during build.

Ignore-AOSP-First: config.apiLibraries list differ between AOSP and internal master
Test: enable disabled modules in java/core-libraries/TxtStubLibraries.bp then m art.module.public.api.stubs.from-text --build-from-text-stub
