Add exported_java_aconfig_library
Add a rule to generate a JAR file containing code for all aconfig flags
in all packages. This is intended for apps compiled outside the
platform.
Also add a rule to include the new JAR file among the SDK artifacts.
Note: a future CL will refine the aconfig command line options used, or
filter the aconfig output: right now the JAR really contains *all*
flags; we want it to include only *exported* flags.
Bug: 311151343
Test: m sdk dist # manually verify that this generates $(gettop)/out/dist/android-flags.jar
