[android] include all locales in resource packing bundles

This CL makes it so that all locales are used during resource_packaging
for bundle builds.

It is a reland of: https://crrev.com/c/2024159 which included the new
locales on APK builds and was reverted.

Before this change all language splits for the 27 + 9 new languages
recently added to Clank were about half the size as older languages in
monochrome_public_bundle.apks

After this change the new languages and old languages are about the same
size in monochrome_public_bundle.apks.

Example Before (af,as, az, be, bn, and bs are new languages):
