Adam Lesinski 34a1687a67 AAPT2: Remove resources that define locales but no default values.
According to our docs:
https://developer.android.com/guide/topics/resources/localization.html#defaults-r-important

Some resources *require* that there is a default definition. So far,
the pain is felt when doing translations for strings that have been
renamed, etc.

This CL strips out resources that don't have a default value and define
a resource for a locale. This is conservative, but should be expanded
to other configuration properties moving forward.

Bug: 36572857
Test: make aapt2_tests
