Add explicit dependency from android.test.base to hiddenapi annotations

Previously, the dependency was implicit by name. This change makes it
explicit.

The android.test.base-hiddenapi is renamed to prevent the implicit
dependency being discovered. A follow up change will remove that
capability from Soong.

Test: m droid
      Verified that hiddenapi files (both aggregated ones and for the
      individual modules) are not affected by this change.
